docs: fix plugin config + store + dependency docs

PLUGIN_STORE_GUIDE.md
- 19 occurrences of port 5050 -> 5000
- All API paths missing /v3 (e.g. /api/plugins/install ->
  /api/v3/plugins/install). Bulk fix.

PLUGIN_REGISTRY_SETUP_GUIDE.md
- Same port + /api/v3 fixes (3 occurrences each)
- "Go to Plugin Store tab" -> "Open the Plugin Manager tab and scroll
  to the Install from GitHub section" (the real flow for registry
  setup is the GitHub install section, not the Plugin Store search)

PLUGIN_CONFIG_QUICK_START.md
- Port 5001 -> 5000 (5001 is the dev_server.py default, not the web UI)
- "Plugin Store tab" install flow -> real Plugin Manager + Plugin Store
  section + per-plugin tab in second nav row
- Removed reference to PLUGIN_CONFIG_TABS_SUMMARY.md (archived doc)

PLUGIN_CONFIGURATION_TABS.md
- "Plugin Management vs Configuration" section confusingly described
  a "Plugins Tab" that doesn't exist as a single thing. Rewrote to
  describe the real two-piece structure: Plugin Manager tab (browse,
  install, toggle) vs per-plugin tabs (configure individual plugins).

PLUGIN_DEPENDENCY_GUIDE.md
- Port 5001 -> 5000

PLUGIN_DEPENDENCY_TROUBLESHOOTING.md
- Wrong port (8080) and wrong UI nav ("Plugin Store or Plugin
  Management"). Fixed to the real flow.

PLUGIN_QUICK_REFERENCE.md
- "Plugin Location: ./plugins/ directory" -> default is plugin-repos/
  (verified in config/config.template.json:130 and
  display_controller.py:132). plugins/ is a fallback.
- File structure diagram showed plugins/ -> plugin-repos/.
- Web UI install flow: "Plugin Store tab" -> "Plugin Manager tab ->
  Plugin Store section". Also fixed Configure ⚙️ button (doesn't
  exist) and "Drag and drop reorder" (not implemented).
- API examples: replaced ad-hoc Python pseudocode with real curl
  examples against /api/v3/plugins/* endpoints. Pointed at
  REST_API_REFERENCE.md for the full list.
- "Migration Path Phase 1-5" was a roadmap written before the plugin
  system shipped. The plugin system is now stable and live. Removed
  the migration phases as they're history, not a roadmap.
- "Quick Migration" section called scripts/migrate_to_plugins.py
  which doesn't exist anywhere in the repo. Removed.
- "Plugin Registry Structure" referenced
  ChuckBuilds/ledmatrix-plugin-registry which doesn't exist. The
  real registry is ChuckBuilds/ledmatrix-plugins. Fixed.
- "Next Steps" / "Questions to Resolve" sections were
  pre-implementation planning notes. Replaced with a "Known
  Limitations" section that documents the actually-real gaps
  (sandboxing, resource limits, ratings, auto-updates).

+# LEDMatrix
+
+## Project Structure
+- `src/plugin_system/` — Plugin loader, manager, store manager, base plugin class
+- `web_interface/` — Flask web UI (blueprints, templates, static JS)
+- `config/config.json` — User plugin configuration (persists across plugin reinstalls)
+- `plugins/` — Installed plugins directory (gitignored)
+- `plugin-repos/` — Development symlinks to monorepo plugin dirs
+
+## Plugin System
+- Plugins inherit from `BasePlugin` in `src/plugin_system/base_plugin.py`
+- Required abstract methods: `update()`, `display(force_clear=False)`
+- Each plugin needs: `manifest.json`, `config_schema.json`, `manager.py`, `requirements.txt`
+- Plugin instantiation args: `plugin_id, config, display_manager, cache_manager, plugin_manager`
+- Config schemas use JSON Schema Draft-7
+- Display dimensions: always read dynamically from `self.display_manager.matrix.width/height`
+
+## Plugin Store Architecture
+- Official plugins live in the `ledmatrix-plugins` monorepo (not individual repos)
+- Plugin repo naming convention: `ledmatrix-<plugin-id>` (e.g., `ledmatrix-football-scoreboard`)
+- `plugins.json` registry at `https://raw.githubusercontent.com/ChuckBuilds/ledmatrix-plugins/main/plugins.json`
+- Store manager (`src/plugin_system/store_manager.py`) handles install/update/uninstall
+- Monorepo plugins are installed via ZIP extraction (no `.git` directory)
+- Update detection for monorepo plugins uses version comparison (manifest version vs registry latest_version)
+- Plugin configs stored in `config/config.json`, NOT in plugin directories — safe across reinstalls
+- Third-party plugins can use their own repo URL with empty `plugin_path`
+
+## Common Pitfalls
+- paho-mqtt 2.x needs `callback_api_version=mqtt.CallbackAPIVersion.VERSION1` for v1 compat
+- BasePlugin uses `get_logger()` from `src.logging_config`, not standard `logging.getLogger()`
+- When modifying a plugin in the monorepo, you MUST bump `version` in its `manifest.json` and run `python update_registry.py` — otherwise users won't receive the update

+The identity of the designer(s) of the original ASCII repertoire and

+Unicode versions of the X11 "misc-fixed-*" fonts
+------------------------------------------------
+
+Markus Kuhn <http://www.cl.cam.ac.uk/~mgk25/> -- 2008-04-21
+
+
+This package contains the X Window System bitmap fonts
+
+   -Misc-Fixed-*-*-*--*-*-*-*-C-*-ISO10646-1
+
+These are Unicode (ISO 10646-1) extensions of the classic ISO 8859-1
+X11 terminal fonts that are widely used with many X11 applications
+such as xterm, emacs, etc.
+
+COVERAGE
+--------
+
+None of these fonts covers Unicode completely. Complete coverage
+simply would not make much sense here. Unicode 5.1 contains over
+100000 characters, and the large majority of them are
+Chinese/Japanese/Korean Han ideographs (~70000) and Korean Hangul
+Syllables (~11000) that cannot adequately be displayed in the small
+pixel sizes of the fixed fonts. Similarly, Arabic characters are
+difficult to fit nicely together with European characters into the
+fixed character cells and X11 lacks the ligature substitution
+mechanisms required for using Indic scripts.
+
+Therefore these fonts primarily attempt to cover Unicode subsets that
+fit together with European scripts. This includes the Latin, Greek,
+Cyrillic, Armenian, Georgian, and Hebrew scripts, plus a lot of
+linguistic, technical and mathematical symbols. Some of the fixed
+fonts now also cover Arabic, Thai, Ethiopian, halfwidth Katakana, and
+some other non-European scripts.
+
+We have defined 3 different target character repertoires (ISO 10646-1
+subsets) that the various fonts were checked against for minimal
+guaranteed coverage:
+
+  TARGET1    617 characters
+             Covers all characters of ISO 8859 part 1-5,7-10,13-16,
+             CEN MES-1, ISO 6937, Microsoft CP1251/CP1252, DEC VT100
+             graphics symbols, and the replacement and default
+             character. It is intended for small bold, italic, and
+             proportional fonts, for which adding block graphics
+             characters would make little sense. This repertoire
+             covers the following ISO 10646-1:2000 collections
+             completely: 1-3, 8, 12.
+
+  TARGET2    886 characters
+             Adds to TARGET1 the characters of the Adobe/Microsoft
+             Windows Glyph List 4 (WGL4), plus a selected set of
+             mathematical characters (covering most of ISO 31-11
+             high-school level math symbols) and some combining
+             characters. It is intended to be covered by all normal
+             "fixed" fonts and covers all European IBM, Microsoft, and
+             Macintosh character sets. This repertoire covers the
+             following ISO 10646-1:2000 (including Amd 1:2002)
+             collections completely: 1-3, 8, 12, 33, 45.
+
+  TARGET3    3282 characters
+
+             Adds to TARGET2 all characters of all European scripts
+             (Latin, Greek, Cyrillic, Armenian, Georgian), all
+             phonetic alphabet symbols, many mathematical symbols
+             (including all those available in LaTeX), all typographic
+             punctuation, all box-drawing characters, control code
+             pictures, graphical shapes and some more that you would
+             expect in a very comprehensive Unicode 4.0 font for
+             European users. It is intended for some of the more
+             useful and more widely used normal "fixed" fonts. This
+             repertoire is, with two exceptions, a superset of all
+             graphical characters in CEN MES-3A and covers the
+             following ISO 10646-1:2000 (including Amd 1:2002)
+             collections completely: 1-12, 27, 30-31, 32 (only
+             graphical characters), 33-42, 44-47, 63, 65, 70 (only
+             graphical characters).
+
+             [The two MES-3A characters deliberately omitted are the
+             angle bracket characters U+2329 and U+232A. ISO and CEN
+             appears to have included these into collection 40 and
+             MES-3A by accident, because there they are the only
+             characters in the Unicode EastAsianWidth "wide" class.]

+achieved easily. Most font mechanisms display a character that is not
+covered in a font by using a glyph from another font that appears
+later in a priority list, which can be arranged to be a "full-width"
+font.]
+
+The supplement package
+
+  http://www.cl.cam.ac.uk/~mgk25/download/ucs-fonts-asian.tar.gz
+
+contains the following additional square fonts with Han characters for
+East Asian users:
+
+   12x13ja.bdf:
+
+     Covers TARGET2, JIS X 0208, Hangul, and a few more. This font is
+     primarily intended to provide Japanese full-width Hiragana,
+     Katakana, and Kanji for applications that take the remaining
+     ("halfwidth") characters from 6x13.bdf. The Greek lowercase
+     characters in it are still a bit ugly and will need some work.
+
+  18x18ja.bdf:
+
+     Covers all JIS X 0208, JIS X 0212, GB 2312-80, KS X 1001:1992,
+     ISO 8859-1,2,3,4,5,7,9,10,15, CP437, CP850 and CP1252 characters,
+     plus a few more, where priority was given to Japanese han style
+     variants. This font should have everything needed to cover the
+     full ISO-2022-JP-2 (RFC 1554) repertoire. This font is primarily
+     intended to provide Japanese full-width Hiragana, Katakana, and
+     Kanji for applications that take the remaining ("halfwidth")
+     characters from 9x18.bdf.
+
+  18x18ko.bdf:
+
+     Covers the same repertoire as 18x18ja plus full coverage of all
+     Hangul syllables and priority was given to Hanja glyphs in the
+     unified CJK area as they are used for writing Korean.
+
+The 9x18 and 6x12 fonts are recommended for use with overstriking
+combining characters.
+
+Bug reports, suggestions for improvement, and especially contributed
+extensions are very welcome!
+
+INSTALLATION
+------------
+
+You install the fonts under Unix roughly like this (details depending
+on your system of course):
+
+System-wide installation (root access required):
+
+  cd submission/
+  make
+  su
+  mv -b *.pcf.gz /usr/lib/X11/fonts/misc/
+  cd /usr/lib/X11/fonts/misc/
+  mkfontdir
+  xset fp rehash
+
+Alternative: Installation in your private user directory:
+
+  cd submission/
+  make
+  mkdir -p ~/local/lib/X11/fonts/
+  mv *.pcf.gz ~/local/lib/X11/fonts/
+  cd ~/local/lib/X11/fonts/
+  mkfontdir
+  xset +fp ~/local/lib/X11/fonts   (put this last line also in ~/.xinitrc)
+
+Now you can have a look at say the 6x13 font with the command
+
+  xfd -fn '-misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso10646-1'
+
+If you want to have short names for the Unicode fonts, you can also
+append the fonts.alias file to that in the directory where you install
+the fonts, call "mkfontdir" and "xset fp rehash" again, and then you
+can also write
+
+  xfd -fn 6x13U
+
+Note: If you use an old version of xfontsel, you might notice that it
+treats every font that contains characters >0x00ff as a Japanese JIS
+font and therefore selects inappropriate sample characters for display
+of ISO 10646-1 fonts. An updated xfontsel version with this bug fixed
+comes with XFree86 4.0 / X11R6.8 or newer.
+
+If you use the Exceed X server on Microsoft Windows, then you will
+have to convert the BDF files into Microsoft FON files using the
+"Compile Fonts" function of Exceed xconfig. See the file exceed.txt
+for more information.
+
+There is one significant efficiency problem that X11R6 has with the
+sparsely populated ISO10646-1 fonts. X11 transmits and allocates 12
+bytes with the XFontStruct data structure for the difference between
+the lowest and the highest code value found in a font, no matter
+whether the code positions in between are used for characters or not.
+Even a tiny font that contains only two glyphs at positions 0x0000 and
+0xfffd causes 12 bytes * 65534 codes = 786 kbytes to be requested and
+stored by the client. Since all the ISO10646-1 BDF files provided in
+this package contain characters in the U+00xx (ASCII) and U+ffxx
+(ligatures, etc.) range, all of them would result in 786 kbyte large
+XCharStruct arrays in the per_char array of the corresponding
+XFontStruct (even for CharCell fonts!) when loaded by an X client.
+Until this problem is fixed by extending the X11 font protocol and
+implementation, non-CJK ISO10646-1 fonts that lack the (anyway not
+very interesting) characters above U+31FF seem to be the best
+compromise. The bdftruncate.pl program in this package can be used to
+deactivate any glyphs above a threshold code value in BDF files. This
+way, we get relatively memory-economic ISO10646-1 fonts that cause
+"only" 150 kbyte large XCharStruct arrays to be allocated. The
+deactivated glyphs are still present in the BDF files, but with an
+encoding value of -1 that causes them to be ignored.
+
+The ISO10646-1 fonts can not only be used directly by Unicode aware
+software, they can also be used to create any 8-bit font. The
+ucs2any.pl Perl script converts a ISO10646-1 BDF font into a BDF font
+file with some different encoding. For instance the command
+
+  perl ucs2any.pl 6x13.bdf MAPPINGS/8859-7.TXT ISO8859-7
+
+will generate the file 6x13-ISO8859-7.bdf according to the 8859-7.TXT
+Latin/Greek mapping table, which available from
+<ftp://ftp.unicode.org/Public/MAPPINGS/>. [The shell script
+./map_fonts automatically generates a subdirectory derived-fonts/ with
+many *.bdf and *.pcf.gz 8-bit versions of all the
+-misc-fixed-*-iso10646-1 fonts.]
+
+When you do a "make" in the submission/ subdirectory as suggested in
+the installation instructions above, this will generate exactly the
+set of fonts that have been submitted to the XFree86 project for
+inclusion into XFree86 4.0. These consists of all the ISO10646-1 fonts
+processed with "bdftruncate.pl U+3200" plus a selected set of derived
+8-bit fonts generated with ucs2any.pl.
+
+Every font comes with a *.repertoire-utf8 file that lists all the
+characters in this font.
+
+
+CONTRIBUTING
+------------
+
+If you want to help me in extending or improving the fonts, or if you
+want to start your own ISO 10646-1 font project, you will have to edit
+BDF font files. This is most comfortably done with the gbdfed font
+editor (version 1.3 or higher), which is available from
+
+    http://crl.nmsu.edu/~mleisher/gbdfed.html
+
+Once you are familiar with gbdfed, you will notice that it is no
+problem to design up to 100 nice characters per hour (even more if
+only placing accents is involved).
+
+Information about other X11 font tools and Unicode fonts for X11 in
+general can be found on
+
+    http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html
+
+The latest version of this package is available from
+
+    http://www.cl.cam.ac.uk/~mgk25/download/ucs-fonts.tar.gz
+
+If you want to contribute, then get the very latest version of this
+package, check which glyphs are still missing or inappropriate for
+your needs, and send me whatever you had the time to add and fix. Just
+email me the extended BDF-files back, or even better, send me a patch
+file of what you changed. The best way of preparing a patch file is
+
+  ./touch_id newfile.bdf
+  diff -d -u -F STARTCHAR oldfile.bdf newfile.bdf >file.diff
+
+which ensures that the patch file preserves information about which
+exact version you worked on and what character each "hunk" changes.
+
+I will try to update this packet on a daily basis. By sending me
+extensions to these fonts, you agree that the resulting improved font
+files will remain in the public domain for everyone's free use. Always
+make sure to load the very latest version of the package immediately
+before your start, and send me your results as soon as you are done,
+in order to avoid revision overlaps with other contributors.
+
+Please try to be careful with the glyphs you generate:
+
+  - Always look first at existing similar characters in order to
+    preserve a consistent look and feel for the entire font and
+    within the font family. For block graphics characters and geometric
+    symbols, take care of correct alignment.
+
+  - Read issues.txt, which contains some design hints for certain
+    characters.
+
+  - All characters of CharCell (C) fonts must strictly fit into
+    the pixel matrix and absolutely no out-of-box ink is allowed.
+
+  - The character cells will be displayed directly next to each other,
+    without any additional pixels in between. Therefore, always make
+    sure that at least the rightmost pixel column remains white, as
+    otherwise letters will stick together, except of course for
+    characters -- like Arabic or block graphics -- that are supposed to
+    stick together.
+
+  - Place accents as low as possible on the Latin characters.
+
+  - Try to keep the shape of accents consistent among each other and
+    with the combining characters in the U+03xx range.
+
+  - Use gbdfed only to edit the BDF file directly and do not import
+    the font that you want to edit from the X server. Use gbdfed 1.3
+    or higher.
+
+  - The glyph names should be the Adobe names for Unicode characters
+    defined at
+
+      http://www.adobe.com/devnet/opentype/archives/glyph.html
+
+    which gbdfed can set automatically. To make the Edit/Rename Glyphs/
+    Adobe Names function work, you have to download the file
+
+      http://www.adobe.com/devnet/opentype/archives/glyphlist.txt
+
+    and configure its location either in Edit/Preferences/Editing Options/
+    Adobe Glyph List, or as "adobe_name_file" in "~/.gbdfed".
+
+  - Be careful to not change the FONTBOUNDINGBOX box accidentally in
+    a patch.
+
+You should have a copy of the ISO 10646 standard
+
+  ISO/IEC 10646:2003, Information technology -- Universal
+  Multiple-Octet Coded Character Set (UCS),
+  International Organization for Standardization, Geneva, 2003.

+All these fonts are from time to time resubmitted to the X.Org
+project, XFree86 (they have been in there since XFree86 4.0), and to
+other X server developers for inclusion into their normal X11
+distributions.
+
+Starting with XFree86 4.0, xterm has included UTF-8 support. This
+version is also available from
+
+  http://dickey.his.com/xterm/xterm.html
+
+Please make the developer of your favourite software aware of the
+UTF-8 definition in RFC 2279 and of the existence of this font

+## Provided fonts
+These are BDF fonts, a simple bitmap font-format that can be created
+by many font tools. Given that these are bitmap fonts, they will look good on
+very low resolution screens such as the LED displays.
+
+Fonts in this directory (except tom-thumb.bdf) are public domain (see the [README](./README)) and
+help you to get started with the font support in the API or the `text-util`
+from the utils/ directory.
+
+Tom-Thumb.bdf is included in this directory under [MIT license](http://vt100.tarunz.org/LICENSE). Tom-thumb.bdf was created by [@robey](http://twitter.com/robey) and originally published at https://robey.lag.net/2010/01/23/tiny-monospace-font.html
+
+The texgyre-27.bdf font was created using the [otf2bdf] tool from the TeX Gyre font.
+```bash
+otf2bdf -v -o texgyre-27.bdf -r 72 -p 27 texgyreadventor-regular.otf
+```
+
+## Create your own
+
+Fonts are in a human-readable and editable `*.bdf` format, but unless you
+like reading and writing pixels in hex, generating them is probably easier :)
+
+You can use any font-editor to generate a BDF font or use the conversion
+tool [otf2bdf] to create one from some other font format.
+
+Here is an example how you could create a 30-pixel high BDF font from some
+TrueType font:
+
+```bash
+otf2bdf -v -o myfont.bdf -r 72 -p 30 /path/to/font-Bold.ttf
+```
+
+## Getting otf2bdf
+
+Installing the tool should be fairly straightforward.
+
+```bash
+sudo apt-get install otf2bdf
+```
+
+## Compiling otf2bdf
+
+If you like to compile otf2bdf, you might notice that the configure script
+uses some old way of getting the freetype configuration. There does not seem
+to be much activity on the mature code, so let's patch that first:
+
+```bash
+sudo apt-get install -y libfreetype6-dev pkg-config autoconf
+git clone https://github.com/jirutka/otf2bdf.git   # check it out
+cd otf2bdf

+# Configuration Debugging Guide
+
+This guide helps troubleshoot configuration issues in LEDMatrix.
+
+## Configuration Files
+
+### Main Files
+
+| File | Purpose |
+|------|---------|
+| `config/config.json` | Main configuration |
+| `config/config_secrets.json` | API keys and sensitive data |
+| `config/config.template.json` | Template for new installations |
+
+### Plugin Configuration
+
+Each plugin's configuration is a top-level key in `config.json`:
+
+```json
+{
+  "football-scoreboard": {
+    "enabled": true,
+    "display_duration": 30,
+    "nfl": {
+      "enabled": true,
+      "live_priority": false
+    }
+  },
+  "odds-ticker": {
+    "enabled": true,
+    "display_duration": 15
+  }
+}
+```
+
+## Schema Validation
+
+Plugins define their configuration schema in `config_schema.json`. This enables:
+- Automatic default value population
+- Configuration validation
+- Web UI form generation
+
+### Missing Schema Warning
+
+If a plugin doesn't have `config_schema.json`, you'll see:
+
+```
+WARNING - Plugin 'my-plugin' has no config_schema.json - configuration will not be validated.
+```
+
+**Fix**: Add a `config_schema.json` to your plugin directory.
+
+### Schema Example
+
+```json
+{
+  "$schema": "http://json-schema.org/draft-07/schema#",
+  "type": "object",
+  "properties": {
+    "enabled": {
+      "type": "boolean",
+      "default": true,
+      "description": "Enable or disable this plugin"
+    },
+    "display_duration": {
+      "type": "number",
+      "default": 15,
+      "minimum": 1,
+      "description": "How long to display in seconds"
+    },
+    "api_key": {
+      "type": "string",
+      "description": "API key for data access"
+    }
+  },
+  "required": ["api_key"]
+}
+```
+
+## Common Configuration Issues
+
+### 1. Type Mismatches
+
+**Problem**: String value where number expected
+
+```json
+{
+  "display_duration": "30"  // Wrong: string
+}
+```
+
+**Fix**: Use correct types
+
+```json
+{
+  "display_duration": 30    // Correct: number
+}
+```
+
+**Logged Warning**:
+```
+WARNING - Config display_duration has invalid string value '30', using default 15.0
+```
+
+### 2. Missing Required Fields
+
+**Problem**: Required field not in config
+
+```json
+{
+  "football-scoreboard": {
+    "enabled": true
+    // Missing api_key which is required
+  }
+}
+```
+
+**Logged Error**:
+```
+ERROR - Plugin football-scoreboard configuration validation failed: 'api_key' is a required property
+```
+
+### 3. Invalid Nested Objects
+
+**Problem**: Wrong structure for nested config
+
+```json
+{
+  "football-scoreboard": {
+    "nfl": "enabled"  // Wrong: should be object
+  }
+}
+```
+
+**Fix**: Use correct structure
+
+```json
+{
+  "football-scoreboard": {
+    "nfl": {
+      "enabled": true
+    }
+  }
+}
+```
+
+### 4. Invalid JSON Syntax
+
+**Problem**: Malformed JSON
+
+```json
+{
+  "plugin": {
+    "enabled": true,  // Trailing comma
+  }
+}
+```
+
+**Fix**: Remove trailing commas, ensure valid JSON
+
+```json
+{
+  "plugin": {
+    "enabled": true
+  }
+}
+```
+
+**Tip**: Validate JSON at https://jsonlint.com/
+
+## Debugging Configuration Loading
+
+### Enable Debug Logging
+
+Set environment variable:
+```bash
+export LEDMATRIX_DEBUG=1
+python run.py
+```
+
+### Check Merged Configuration
+
+The configuration is merged with schema defaults. To see the final merged config:
+
+1. Enable debug logging
+2. Look for log entries like:
+   ```
+   DEBUG - Merged config with schema defaults for football-scoreboard
+   ```
+
+### Configuration Load Order
+
+1. Load `config.json`
+2. Load `config_secrets.json`
+3. Merge secrets into main config
+4. For each plugin:
+   - Load plugin's `config_schema.json`
+   - Extract default values from schema
+   - Merge user config with defaults
+   - Validate merged config against schema
+
+## Web Interface Issues
+
+### Changes Not Saving
+
+1. Check file permissions on `config/` directory
+2. Check disk space
+3. Look for errors in browser console
+4. Check server logs for save errors
+
+### Form Fields Not Appearing
+
+1. Plugin may not have `config_schema.json`
+2. Schema may have syntax errors
+3. Check browser console for JavaScript errors
+
+### Checkboxes Not Working
+
+Boolean values from checkboxes should be actual booleans, not strings:
+
+```json
+{
+  "enabled": true,     // Correct
+  "enabled": "true"    // Wrong
+}
+```
+
+## Config Key Collision Detection
+
+LEDMatrix detects potential config key conflicts:
+
+### Reserved Keys
+
+These plugin IDs will trigger a warning:
+- `display`, `schedule`, `timezone`, `plugin_system`
+- `display_modes`, `system`, `hardware`, `debug`
+- `log_level`, `emulator`, `web_interface`
+
+**Warning**:
+```
+WARNING - Plugin ID 'display' conflicts with reserved config key.
+```
+
+### Case Collisions
+
+Plugin IDs that differ only in case:
+```
+WARNING - Plugin ID 'Football-Scoreboard' may conflict with 'football-scoreboard' on case-insensitive file systems.
+```
+
+## Checking Configuration via API
+
+```bash
+# Get current config
+curl http://localhost:5000/api/v3/config
+
+# Get specific plugin config
+curl http://localhost:5000/api/v3/config/plugin/football-scoreboard
+
+# Validate config without saving
+curl -X POST http://localhost:5000/api/v3/config/validate \
+  -H "Content-Type: application/json" \
+  -d '{"football-scoreboard": {"enabled": true}}'
+```
+
+## Backup and Recovery
+
+### Manual Backup
+
+```bash
+cp config/config.json config/config.backup.json
+```
+
+### Automatic Backups
+
+LEDMatrix creates backups before saves:
+- Location: `config/backups/`
+- Format: `config_YYYYMMDD_HHMMSS.json`
+
+### Recovery
+
+```bash
+# List backups
+ls -la config/backups/
+
+# Restore from backup
+cp config/backups/config_20240115_120000.json config/config.json
+```
+
+## Troubleshooting Checklist

-## Plugin Submodules
+## Plugins
 
-Plugin submodules are located in the `plugins/` directory and are managed similarly:
+Plugins are **not** git submodules of this repository. The plugins
+directory (configured by `plugin_system.plugins_directory` in
+`config/config.json`, default `plugin-repos/`) is populated at install
+time by the plugin loader as users install plugins from the Plugin Store
+or from a GitHub URL via the web interface. Plugin source lives in a
+separate repository:
+[ChuckBuilds/ledmatrix-plugins](https://github.com/ChuckBuilds/ledmatrix-plugins).
 
-**Initialize all plugin submodules:**
-```bash
-git submodule update --init --recursive plugins/
-```
+To work on a plugin locally without going through the Plugin Store, clone
+that repo and symlink (or copy) the plugin directory into your configured
+plugins directory — by default `plugin-repos/<plugin-id>/`. The plugin
+loader will pick it up on the next display restart. The directory name
+must match the plugin's `id` in `manifest.json`.
 
-**Initialize a specific plugin:**
-```bash
-git submodule update --init --recursive plugins/hockey-scoreboard
-```
-
-For more information about plugins, see the [Plugin Development Guide](.cursor/plugins_guide.md) and [Plugin Architecture Specification](docs/PLUGIN_ARCHITECTURE_SPEC.md).

+# Dev Preview & Visual Testing
+
+Tools for rapid plugin development without deploying to the RPi.
+
+## Dev Preview Server
+
+Interactive web UI for tweaking plugin configs and seeing the rendered display in real time.
+
+### Quick Start
+
+```bash
+python scripts/dev_server.py
+# Opens at http://localhost:5001
+```
+
+### Options
+
+```bash
+python scripts/dev_server.py --port 8080                          # Custom port
+python scripts/dev_server.py --extra-dir /path/to/custom-plugin   # 3rd party plugins
+python scripts/dev_server.py --debug                              # Flask debug mode
+```
+
+### Workflow
+
+1. Select a plugin from the dropdown (auto-discovers from `plugins/` and `plugin-repos/`)
+2. The config form auto-generates from the plugin's `config_schema.json`
+3. Tweak any config value — the display preview updates automatically
+4. Toggle "Auto" off for plugins with slow `update()` calls, then click "Render" manually
+5. Use the zoom slider to scale the tiny display (128x32) up for detailed inspection
+6. Toggle the grid overlay to see individual pixel boundaries
+
+### Mock Data for API-dependent Plugins
+
+Many plugins fetch data from APIs (sports scores, weather, stocks). To render these locally, expand "Mock Data" and paste a JSON object with cache keys the plugin expects.
+
+To find the cache keys a plugin uses, search its `manager.py` for `self.cache_manager.set(` calls.
+
+Example for a sports plugin:
+```json
+{
+  "football_scores": {
+    "games": [
+      {"home": "Eagles", "away": "Chiefs", "home_score": 24, "away_score": 21, "status": "Final"}
+    ]
+  }
+}
+```
+
+---
+
+## CLI Render Script
+
+Render any plugin to a PNG image from the command line. Useful for AI-assisted development and scripted workflows.
+
+### Usage
+
+```bash
+# Basic — renders with default config
+python scripts/render_plugin.py --plugin hello-world --output /tmp/hello.png
+
+# Custom config
+python scripts/render_plugin.py --plugin clock-simple \
+  --config '{"timezone":"America/New_York","time_format":"12h"}' \
+  --output /tmp/clock.png
+
+# Different display dimensions
+python scripts/render_plugin.py --plugin hello-world --width 64 --height 32 --output /tmp/small.png
+
+# 3rd party plugin from a custom directory
+python scripts/render_plugin.py --plugin my-plugin --plugin-dir /path/to/repo --output /tmp/my.png
+
+# With mock API data
+python scripts/render_plugin.py --plugin football-scoreboard \
+  --mock-data /tmp/mock_scores.json \
+  --output /tmp/football.png
+```
+
+### Using with Claude Code / AI
+
+Claude can run the render script, then read the output PNG (Claude is multimodal and can see images). This enables a visual feedback loop:
+
+```bash
+Claude → bash: python scripts/render_plugin.py --plugin hello-world --output /tmp/render.png
+Claude → Read /tmp/render.png   ← Claude sees the actual rendered display
+Claude → (makes code changes based on what it sees)
+Claude → bash: python scripts/render_plugin.py --plugin hello-world --output /tmp/render2.png
+Claude → Read /tmp/render2.png  ← verifies the visual change
+```
+
+---
+
+## VisualTestDisplayManager (for test suites)
+
+A display manager that renders real pixels for use in pytest, without requiring hardware.
+
+### Basic Usage
+
+```python
+from src.plugin_system.testing import VisualTestDisplayManager, MockCacheManager, MockPluginManager
+
+def test_my_plugin_renders_title():
+    display = VisualTestDisplayManager(width=128, height=32)
+    cache = MockCacheManager()
+    pm = MockPluginManager()
+
+    plugin = MyPlugin(
+        plugin_id='my-plugin',
+        config={'enabled': True, 'title': 'Hello'},
+        display_manager=display,
+        cache_manager=cache,
+        plugin_manager=pm
+    )
+
+    plugin.update()
+    plugin.display(force_clear=True)
+
+    # Verify pixels were drawn (not just that methods were called)
+    pixels = list(display.image.getdata())
+    assert any(p != (0, 0, 0) for p in pixels), "Display should not be blank"
+
+    # Save snapshot for manual inspection
+    display.save_snapshot('/tmp/test_my_plugin.png')
+```
+
+### Pytest Fixture
+
+A `visual_display_manager` fixture is available in plugin tests:
+
+```python
+def test_rendering(visual_display_manager):
+    visual_display_manager.draw_text("Test", x=10, y=10, color=(255, 255, 255))
+    assert visual_display_manager.width == 128
+    pixels = list(visual_display_manager.image.getdata())
+    assert any(p != (0, 0, 0) for p in pixels)
+```
+
+### Key Differences from MockDisplayManager
+
+| Feature | MockDisplayManager | VisualTestDisplayManager |
+|---------|-------------------|--------------------------|
+| Renders pixels | No (logs calls only) | Yes (real PIL rendering) |
+| Loads fonts | No | Yes (same fonts as production) |
+| Save to PNG | No | Yes (`save_snapshot()`) |
+| Call tracking | Yes | Yes (backwards compatible) |
+| Use case | Unit tests (method call assertions) | Visual tests, dev preview |
+
+---
+
+## Plugin Test Runner
+
+The test runner auto-detects `plugin-repos/` for monorepo development:
+
+```bash
+# Auto-detect (tries plugins/ then plugin-repos/)
+python scripts/run_plugin_tests.py
+
+# Test specific plugin
+python scripts/run_plugin_tests.py --plugin clock-simple
+
+# Explicit directory
+python scripts/run_plugin_tests.py --plugins-dir plugin-repos/
+
+# With coverage
+python scripts/run_plugin_tests.py --coverage --verbose
+```

+# Getting Started with LEDMatrix
+
+## Welcome
+
+This guide will help you set up your LEDMatrix display for the first time and get it running in under 30 minutes.
+
+---
+
+## Prerequisites
+
+**Hardware:**
+- Raspberry Pi (3, 4, or 5 recommended)
+- RGB LED Matrix panel (32x64 or 64x64)
+- Adafruit RGB Matrix HAT or similar
+- Power supply (5V, 4A minimum recommended)
+- MicroSD card (16GB minimum)
+
+**Network:**
+- WiFi network (or Ethernet cable)
+- Computer with web browser on same network
+
+---
+
+## Quick Start (5 Minutes)
+
+### 1. First Boot
+
+1. Insert the MicroSD card with LEDMatrix installed
+2. Connect the LED matrix to your Raspberry Pi
+3. Plug in the power supply
+4. Wait for the Pi to boot (about 60 seconds)
+
+**Expected Behavior:**
+- LED matrix will light up
+- Display will show default plugins (clock, weather, etc.)
+- Pi creates WiFi network "LEDMatrix-Setup" if not connected
+
+### 2. Connect to WiFi
+
+**If you see "LEDMatrix-Setup" WiFi network:**
+1. Connect your device to "LEDMatrix-Setup" (open network, no password)
+2. Open browser to: `http://192.168.4.1:5000`
+3. Navigate to the WiFi tab
+4. Click "Scan" to find your WiFi network
+5. Select your network, enter password
+6. Click "Connect"
+7. Wait for connection (LED matrix will show confirmation)
+
+**If already connected to WiFi:**
+1. Find your Pi's IP address (check your router, or run `hostname -I` on the Pi)
+2. Open browser to: `http://your-pi-ip:5000`
+
+### 3. Access the Web Interface
+
+Once connected, access the web interface:
+
+```
+http://your-pi-ip:5000
+```
+
+You should see:
+- Overview tab with system stats
+- Live display preview
+- Quick action buttons
+
+---
+
+## Initial Configuration (15 Minutes)
+
+### Step 1: Configure Display Hardware
+
+1. Open the **Display** tab
+2. Set your matrix configuration:
+   - **Rows**: 32 or 64 (match your hardware)
+   - **Columns**: 64 or 96 (match your hardware)
+   - **Chain Length**: Number of panels chained horizontally
+   - **Hardware Mapping**: usually `adafruit-hat-pwm` (with the PWM jumper
+     mod) or `adafruit-hat` (without). See the root README for the full list.
+   - **Brightness**: 70–90 is fine for indoor use
+3. Click **Save**
+4. From the **Overview** tab, click **Restart Display Service** to apply
+
+**Tip:** if the display shows garbage or nothing, the most common culprits
+are an incorrect `hardware_mapping`, a `gpio_slowdown` value that doesn't
+match your Pi model, or panels needing the E-line mod. See
+[TROUBLESHOOTING.md](TROUBLESHOOTING.md).
+
+### Step 2: Set Timezone and Location
+
+1. Open the **General** tab
+2. Set your timezone (e.g., `America/New_York`) and location
+3. Click **Save**
+
+Correct timezone ensures accurate time display, and location is used by
+weather and other location-aware plugins.
+
+### Step 3: Install Plugins
+
+1. Open the **Plugin Manager** tab
+2. Scroll to the **Plugin Store** section to browse available plugins
+3. Click **Install** on the plugins you want
+4. Wait for installation to finish — installed plugins appear in the
+   **Installed Plugins** section above and get their own tab in the second
+   nav row
+5. Toggle the plugin to enabled
+6. From **Overview**, click **Restart Display Service**
+
+You can also install community plugins straight from a GitHub URL using the
+**Install from GitHub** section further down the same tab — see
+[PLUGIN_STORE_GUIDE.md](PLUGIN_STORE_GUIDE.md) for details.
+
+### Step 4: Configure Plugins
+
+1. Each installed plugin gets its own tab in the second navigation row
+2. Open that plugin's tab to edit its settings (favorite teams, API keys,
+   update intervals, display duration, etc.)
+3. Click **Save**
+4. Restart the display service from **Overview** so the new settings take
+   effect
+
+**Example: Weather Plugin**
+- Set your location (city, state, country)
+- Add an API key from OpenWeatherMap (free signup) to
+  `config/config_secrets.json` or directly in the plugin's config screen
+- Set the update interval (300 seconds is reasonable)
+
+---
+
+## Testing Your Display
+
+### Run a single plugin on demand
+
+The fastest way to verify a plugin works without waiting for the rotation:
+
+1. Open the plugin's tab (second nav row)
+2. Scroll to **On-Demand Controls**
+3. Click **Run On-Demand** — the plugin runs immediately even if disabled
+4. Click **Stop On-Demand** to return to the normal rotation
+
+### Check the live preview and logs
+
+- The **Overview** tab shows a **Live Display Preview** that mirrors what's
+  on the matrix in real time — handy for debugging without looking at the
+  panel.
+- The **Logs** tab streams the display and web service logs. Look for
+  `ERROR` lines if something isn't working; normal operation just shows
+  `INFO` messages about plugin rotation.
+
+---
+
+## Common First-Time Issues
+
+### Display Not Showing Anything
+
+**Check:**
+1. Power supply connected and adequate (5V, 4A minimum)
+2. LED matrix connected to the bonnet/HAT correctly
+3. Display service running: `sudo systemctl status ledmatrix`
+4. Hardware configuration matches your matrix (rows/cols/chain length)
+
+**Fix:**
+1. Restart from the **Overview** tab → **Restart Display Service**
+2. Or via SSH: `sudo systemctl restart ledmatrix`
+
+### Web Interface Won't Load
+
+**Check:**
+1. Pi is connected to network: `ping your-pi-ip`
+2. Web service running: `sudo systemctl status ledmatrix-web`
+3. Correct port: the web UI listens on `:5000`
+4. Firewall not blocking port 5000
+
+**Fix:**
+1. Restart web service: `sudo systemctl restart ledmatrix-web`
+2. Check logs: `sudo journalctl -u ledmatrix-web -n 50`
+
+### Plugins Not Showing
+
+**Check:**
+1. Plugin is enabled (toggle on the **Plugin Manager** tab)
+2. Display service was restarted after enabling
+3. Plugin's display duration is non-zero
+4. No errors in the **Logs** tab for that plugin
+
+**Fix:**
+1. Enable the plugin from **Plugin Manager**
+2. Click **Restart Display Service** on **Overview**
+3. Check the **Logs** tab for plugin-specific errors
+
+### Weather Plugin Shows "No Data"
+
+**Check:**
+1. API key configured (OpenWeatherMap)
+2. Location is correct (city, state, country)
+3. Internet connection working
+
+**Fix:**
+1. Sign up at openweathermap.org (free)
+2. Add API key to config_secrets.json or plugin config
+3. Restart display
+
+---
+
+## Next Steps
+
+### Customize Your Display
+
+**Adjust display durations:**
+- Each plugin's tab has a **Display Duration (seconds)** field — set how
+  long that plugin stays on screen each rotation.
+
+**Organize plugin order:**
+- Use the **Plugin Manager** tab to enable/disable plugins. The display
+  cycles through enabled plugins in the order they appear.
+
+**Add more plugins:**
+- Check the **Plugin Store** section of **Plugin Manager** for new plugins.
+- Install community plugins straight from a GitHub URL via
+  **Install from GitHub** on the same tab.

@@ -114,6 +114,95 @@ Get display duration for this plugin. Can be overridden for dynamic durations.
 
 Return plugin info for display in web UI. Override to provide additional state information.
 
+### Dynamic-duration hooks
+
+Plugins that render multi-step content (e.g. cycling through several games)
+can extend their display time until they've shown everything. To opt in,
+either set `dynamic_duration.enabled: true` in the plugin's config or
+override `supports_dynamic_duration()`.
+
+#### `supports_dynamic_duration() -> bool`
+
+Return `True` if this plugin should use dynamic durations. Default reads
+`config["dynamic_duration"]["enabled"]`.
+
+#### `get_dynamic_duration_cap() -> Optional[float]`
+
+Maximum number of seconds the controller will keep this plugin on screen
+in dynamic mode. Default reads
+`config["dynamic_duration"]["max_duration_seconds"]`.
+
+#### `is_cycle_complete() -> bool`
+
+Override this to return `True` only after the plugin has rendered all of
+its content for the current rotation. Default returns `True` immediately,
+which means a single `display()` call counts as a full cycle.
+
+#### `reset_cycle_state() -> None`
+
+Called by the controller before each new dynamic-duration session. Reset
+internal counters/iterators here.
+
+### Live priority hooks
+
+Live priority lets a plugin temporarily take over the rotation when it has
+urgent content (live games, breaking news). Enable by setting
+`live_priority: true` in the plugin's config and overriding
+`has_live_content()`.
+
+#### `has_live_priority() -> bool`
+
+Whether live priority is enabled in config (default reads
+`config["live_priority"]`).
+
+#### `has_live_content() -> bool`
+
+Override to return `True` when the plugin currently has urgent content.
+Default returns `False`.
+
+#### `get_live_modes() -> List[str]`
+
+List of display modes to show during a live takeover. Default returns the
+plugin's `display_modes` from its manifest.
+
+### Vegas scroll hooks
+
+Vegas mode shows multiple plugins as a single continuous scroll instead of
+rotating one at a time. Plugins control how their content appears via
+these hooks. See [ADVANCED_FEATURES.md](ADVANCED_FEATURES.md) for the user
+side of Vegas mode.
+
+#### `get_vegas_content() -> Optional[PIL.Image | List[PIL.Image] | None]`
+
+Return content to inject into the scroll. Multi-item plugins (sports,
+odds, news) should return a *list* of PIL Images so each item scrolls
+independently. Static plugins (clock, weather) can return a single image.
+Returning `None` falls back to capturing whatever `display()` produces.
+
+#### `get_vegas_content_type() -> str`
+
+`'multi'`, `'static'`, or `'none'`. Affects how Vegas mode treats the
+plugin. Default `'static'`.
+
+#### `get_vegas_display_mode() -> VegasDisplayMode`
+
+Returns one of `VegasDisplayMode.SCROLL`, `FIXED_SEGMENT`, or `STATIC`.
+Read from `config["vegas_mode"]` or override directly.
+
+#### `get_supported_vegas_modes() -> List[VegasDisplayMode]`
+
+The set of Vegas modes this plugin can render. Used by the UI to populate
+the mode selector for this plugin.
+
+#### `get_vegas_segment_width() -> Optional[int]`
+
+For `FIXED_SEGMENT` plugins, the width in pixels of the segment they
+occupy in the scroll. `None` lets the controller pick a default.

 ### Image Rendering
 
-#### `draw_image(image: PIL.Image, x: int, y: int) -> None`

-- `y` (int): Y position (top edge)

+# Plugin Error Handling Guide
+
+This guide covers best practices for error handling in LEDMatrix plugins.
+
+## Custom Exception Hierarchy
+
+LEDMatrix provides typed exceptions for different error categories. Use these instead of generic `Exception`:
+
+```python
+from src.exceptions import PluginError, ConfigError, CacheError, DisplayError
+
+# Plugin-related errors
+raise PluginError("Failed to fetch data", plugin_id=self.plugin_id, context={"api": "ESPN"})
+
+# Configuration errors
+raise ConfigError("Invalid API key format", field="api_key")
+
+# Cache errors
+raise CacheError("Cache write failed", cache_key="game_data")
+
+# Display errors
+raise DisplayError("Failed to render", display_mode="live")
+```
+
+### Exception Context
+
+All LEDMatrix exceptions support a `context` dict for additional debugging info:
+
+```python
+raise PluginError(
+    "API request failed",
+    plugin_id=self.plugin_id,
+    context={
+        "url": api_url,
+        "status_code": response.status_code,
+        "retry_count": 3
+    }
+)
+```
+
+## Logging Best Practices
+
+### Use the Plugin Logger
+
+Every plugin has access to `self.logger`:
+
+```python
+class MyPlugin(BasePlugin):
+    def update(self):
+        self.logger.info("Starting data fetch")
+        self.logger.debug("API URL: %s", api_url)
+        self.logger.warning("Rate limit approaching")
+        self.logger.error("API request failed", exc_info=True)
+```
+
+### Log Levels
+
+- **DEBUG**: Detailed info for troubleshooting (API URLs, parsed data)
+- **INFO**: Normal operation milestones (plugin loaded, data fetched)
+- **WARNING**: Recoverable issues (rate limits, cache miss, fallback used)
+- **ERROR**: Failures that need attention (API down, display error)
+
+### Include exc_info for Exceptions
+
+```python
+try:
+    response = requests.get(url)
+except requests.RequestException as e:
+    self.logger.error("API request failed: %s", e, exc_info=True)
+```
+
+## Error Handling Patterns
+
+### Never Use Bare except
+
+```python
+# BAD - swallows all errors including KeyboardInterrupt
+try:
+    self.fetch_data()
+except:
+    pass
+
+# GOOD - catch specific exceptions
+try:
+    self.fetch_data()
+except requests.RequestException as e:
+    self.logger.warning("Network error, using cached data: %s", e)
+    self.data = self.get_cached_data()
+```
+
+### Graceful Degradation
+
+```python
+def update(self):
+    try:
+        self.data = self.fetch_live_data()
+    except requests.RequestException as e:
+        self.logger.warning("Live data unavailable: %s", e)
+        # Fall back to cache
+        cached = self.cache_manager.get(self.cache_key)
+        if cached:
+            self.logger.info("Using cached data")
+            self.data = cached
+        else:
+            self.logger.error("No cached data available")
+            self.data = None
+```
+
+### Validate Configuration Early
+
+```python
+def validate_config(self) -> bool:
+    """Validate configuration at load time."""
+    api_key = self.config.get("api_key")
+    if not api_key:
+        self.logger.error("api_key is required but not configured")
+        return False
+
+    if not isinstance(api_key, str) or len(api_key) < 10:
+        self.logger.error("api_key appears to be invalid")
+        return False
+
+    return True
+```
+
+### Handle Display Errors
+
+```python
+def display(self, force_clear: bool = False) -> bool:
+    if not self.data:
+        if force_clear:
+            self.display_manager.clear()
+            self.display_manager.update_display()
+        return False
+
+    try:
+        self._render_content()
+        return True
+    except Exception as e:
+        self.logger.error("Display error: %s", e, exc_info=True)
+        # Clear display on error to prevent stale content
+        self.display_manager.clear()
+        self.display_manager.update_display()
+        return False
+```
+
+## Error Aggregation
+
+LEDMatrix automatically tracks plugin errors. Access error data via the API:
+
+```bash
+# Get error summary
+curl http://localhost:5000/api/v3/errors/summary
+
+# Get plugin-specific health
+curl http://localhost:5000/api/v3/errors/plugin/my-plugin
+
+# Clear old errors
+curl -X POST http://localhost:5000/api/v3/errors/clear
+```
+
+### Error Patterns
+
+When the same error occurs repeatedly (5+ times in 60 minutes), it's detected as a pattern and logged as a warning. This helps identify systemic issues.
+
+## Common Error Scenarios
+
+### API Rate Limiting
+
+```python
+def fetch_data(self):
+    try:
+        response = requests.get(self.api_url)
+        if response.status_code == 429:
+            retry_after = int(response.headers.get("Retry-After", 60))
+            self.logger.warning("Rate limited, retry after %ds", retry_after)
+            self._rate_limited_until = time.time() + retry_after
+            return None
+        response.raise_for_status()
+        return response.json()
+    except requests.RequestException as e:
+        self.logger.error("API error: %s", e)
+        return None
+```
+
+### Timeout Handling
+
+```python
+def fetch_data(self):
+    try:
+        response = requests.get(self.api_url, timeout=10)
+        return response.json()
+    except requests.Timeout:
+        self.logger.warning("Request timed out, will retry next update")
+        return None
+    except requests.RequestException as e:
+        self.logger.error("Request failed: %s", e)
+        return None
+```
+
+### Missing Data Gracefully
+
+```python
+def get_team_logo(self, team_id):
+    logo_path = self.logos_dir / f"{team_id}.png"
+    if not logo_path.exists():
+        self.logger.debug("Logo not found for team %s, using default", team_id)
+        return self.default_logo
+    return Image.open(logo_path)
+```
+
+## Testing Error Handling
+
+```python
+def test_handles_api_error(mock_requests):
+    """Test plugin handles API errors gracefully."""
+    mock_requests.get.side_effect = requests.RequestException("Network error")
+
+    plugin = MyPlugin(...)
+    plugin.update()
+
+    # Should not raise, should log warning, should have no data
+    assert plugin.data is None
+
+def test_handles_invalid_json(mock_requests):
+    """Test plugin handles invalid JSON response."""
+    mock_requests.get.return_value.json.side_effect = ValueError("Invalid JSON")
+
+    plugin = MyPlugin(...)
+    plugin.update()
+
+    assert plugin.data is None
+```
+

+LEDMatrix is a modular, plugin-based system where users create, share,
+and install custom displays via a GitHub-based store (similar in spirit
+to HACS for Home Assistant). This page is a quick reference; for the
+full design see [PLUGIN_ARCHITECTURE_SPEC.md](PLUGIN_ARCHITECTURE_SPEC.md)
+and [PLUGIN_DEVELOPMENT_GUIDE.md](PLUGIN_DEVELOPMENT_GUIDE.md).
 
 ## Key Decisions
 
-✅ **Gradual Migration**: Existing managers stay, plugins added alongside  
-✅ **Migration Required**: Breaking changes in v3.0, tools provided  
-✅ **GitHub Store**: Simple discovery, packages from repos  
-✅ **Plugin Location**: `./plugins/` directory  
+✅ **Plugin-First**: All display features (calendar excepted) are now plugins
+✅ **GitHub Store**: Discovery from `ledmatrix-plugins` registry plus
+   any GitHub URL
+✅ **Plugin Location**: configured by `plugin_system.plugins_directory`
+   in `config.json` (default `plugin-repos/`; the loader also searches
+   `plugins/` as a fallback)

 - ✅ Community handles custom displays
 - ✅ Easier to review changes
 
-## What's Missing?
+## Known Limitations
 
-This specification covers the technical architecture. Additional considerations:
+The plugin system is shipped and stable, but some things are still
+intentionally simple:
 
-1. **Sandboxing**: Current design has no isolation (future enhancement)
-2. **Resource Limits**: No CPU/memory limits per plugin (future)
-3. **Plugin Ratings**: Registry needs rating/review system
-4. **Auto-Updates**: Manual update only (could add auto-update)
-5. **Dependency Conflicts**: No automatic resolution
-6. **Version Pinning**: Limited version constraint checking
-7. **Plugin Testing**: No automated testing framework
-8. **Marketplace**: No paid plugins (all free/open source)
-
-## Next Steps
-
-1. ✅ Review this specification
-2. Start Phase 1 implementation
-3. Create first 3-4 example plugins
-4. Set up plugin registry repo
-5. Build web UI components
-6. Test on Pi hardware
-7. Release v2.0.0 alpha
-
-## Questions to Resolve
-
-Before implementing, consider:
-
-1. Should we support plugin dependencies (plugin A requires plugin B)?
-2. How to handle breaking changes in core display_manager API?
-3. Should plugins be able to add new web UI pages?
-4. What about plugins that need hardware beyond LED matrix?
-5. How to prevent malicious plugins?
-6. Should there be plugin quotas (max API calls, etc.)?
-7. How to handle plugin conflicts (two clocks competing)?
+1. **Sandboxing**: plugins run in the same process as the display loop;
+   there is no isolation. Review code before installing third-party
+   plugins.
+2. **Resource limits**: there's a resource monitor that warns about
+   slow plugins, but no hard CPU/memory caps.
+3. **Plugin ratings**: not yet — the Plugin Store shows version,
+   author, and category but no community rating system.
+4. **Auto-updates**: manual via the Plugin Manager tab; no automatic
+   background updates.
+5. **Dependency conflicts**: each plugin's `requirements.txt` is
+   installed via pip; conflicting versions across plugins are not
+   resolved automatically.
+6. **Plugin testing framework**: see
+   [HOW_TO_RUN_TESTS.md](HOW_TO_RUN_TESTS.md) and
+   [DEV_PREVIEW.md](DEV_PREVIEW.md) — there are tools, but no
+   mandatory test gate.

+```
+
+**Via Python:**
+```python
+from src.plugin_system.store_manager import PluginStoreManager
+
+store = PluginStoreManager()
+result = store.install_from_url('https://github.com/user/ledmatrix-my-plugin')
+
+if result['success']:
+    print(f"Installed: {result['plugin_id']}")
+else:
+    print(f"Error: {result['error']}")
+```
+
+---
+
+## Searching for Plugins
+
+**Via Web Interface:**
+- Use the search bar to search by name, description, or author
+- Filter by category (sports, weather, time, finance, etc.)
+- Click on tags to filter by specific tags
+
+**Via REST API:**
+```bash
+# Search by query
+curl "http://your-pi-ip:5000/api/v3/plugins/store/search?q=hockey"
+
+# Filter by category
+curl "http://your-pi-ip:5000/api/v3/plugins/store/search?category=sports"
+

+```
+
+**Via Python:**
+```python
+from src.plugin_system.store_manager import PluginStoreManager
+
+store = PluginStoreManager()
+
+# Search by query
+results = store.search_plugins(query="hockey")
+
+# Filter by category
+results = store.search_plugins(category="sports")
+
+# Filter by tags
+results = store.search_plugins(tags=["nhl", "hockey"])
+```
+

+    "enabled": true,
+    "display_duration": 15,
+    "color": [255, 255, 255],
+    "time_format": "12h"
+  },
+  "nhl-scores": {
+    "enabled": true,
+    "favorite_teams": ["TBL", "FLA"],
+    "show_favorite_teams_only": true
+  }
+}
+```
+
+**Via Web Interface:**
+1. Navigate to the "Plugin Manager" tab
+2. Click the Configure (⚙️) button next to the plugin
+3. Edit the configuration in the form
+4. Save changes
+5. Restart the display to apply changes
+
+---
+
+## Safety and Security
+
+### Verified vs Unverified Plugins
+
+- **Verified Plugins**: Reviewed by maintainers, follow best practices, no known security issues
+- **Unverified Plugins**: User-contributed, not reviewed, install at your own risk
+
+When installing from a custom GitHub URL, you'll see a warning about installing an unverified plugin. The plugin will have access to your display manager, cache manager, configuration files, and network access.
+
+### Best Practices
+
+1. Only install plugins from trusted sources
+2. Review plugin code before installing (click "View on GitHub")
+3. Keep plugins updated for security patches
+4. Report suspicious plugins to maintainers
+
+---
+
+## Troubleshooting
+
+### Plugin Won't Install
+
+**Problem:** Installation fails with "Failed to clone or download repository"
+
+**Solutions:**
+- Check that git is installed: `which git`
+- Verify the GitHub URL is correct
+- Check your internet connection
+- The system will automatically try ZIP download as fallback
+
+### Plugin Won't Load
+
+**Problem:** Plugin installed but doesn't appear in rotation
+
+**Solutions:**
+1. Check that the plugin is enabled in config: `"enabled": true`
+2. Verify manifest.json exists and is valid
+3. Check logs for errors: `sudo journalctl -u ledmatrix -f`
+4. Restart the display service: `sudo systemctl restart ledmatrix`
+
+### Dependencies Failed
+
+**Problem:** "Error installing dependencies" message
+
+**Solutions:**
+- Check that pip3 is installed
+- Manually install: `pip3 install --break-system-packages -r plugins/plugin-id/requirements.txt`
+- Check for conflicting package versions
+
+### Plugin Shows Errors
+
+**Problem:** Plugin loads but shows error message on display
+
+**Solutions:**
+1. Check that the plugin configuration is correct
+2. Verify API keys are set (if the plugin requires them)
+3. Check plugin logs: `sudo journalctl -u ledmatrix -f | grep plugin-id`
+4. Report the issue to the plugin developer on GitHub
+
+---
+
+## API Reference
+
+All API endpoints return JSON with this structure:
+
+```json
+{
+  "status": "success" | "error",
+  "message": "Human-readable message",
+  "data": { ... }
+}
+```
+
+### Endpoints

+
+## FAQ
+
+**Q: Do I need to restart the display after installing a plugin?**
+A: Yes, plugins are loaded when the display controller starts.
+
+**Q: Can I install plugins while the display is running?**
+A: Yes, you can install anytime, but you must restart the display to load them.
+
+**Q: What happens if I install a plugin with the same ID as an existing one?**
+A: The existing copy will be replaced with the latest code from the repository.
+
+**Q: Can I install multiple versions of the same plugin?**
+A: No, each plugin ID maps to a single checkout of the repository's default branch.
+
+**Q: How do I update all plugins at once?**
+A: Currently, you need to update each plugin individually. Bulk update is planned for a future release.
+
+**Q: Can plugins access my API keys from config_secrets.json?**
+A: Yes, if a plugin needs API keys, it can access them like core managers do.
+
+**Q: How much disk space do plugins use?**
+A: Most plugins are small (1-5MB). Check individual plugin documentation for specific requirements.
+
+**Q: Can I create my own plugin?**
+A: Yes! See [PLUGIN_DEVELOPMENT.md](PLUGIN_DEVELOPMENT.md) for instructions.

+# Starlark Apps Guide
+
+## Overview
+
+The Starlark Apps plugin for LEDMatrix enables you to run **Tidbyt/Tronbyte community apps** on your LED matrix display without modification. This integration allows you to access hundreds of pre-built widgets and apps from the vibrant Tidbyt community ecosystem.
+
+## Important: Third-Party Content
+
+**⚠️ Apps are NOT managed by the LEDMatrix project**
+
+- Starlark apps are developed and maintained by the **Tidbyt/Tronbyte community**
+- LEDMatrix provides the runtime environment but does **not** create, maintain, or support these apps
+- All apps originate from the [Tronbyte Apps Repository](https://github.com/tronbyt/apps)
+- App quality, functionality, and security are the responsibility of individual app authors
+- LEDMatrix is not affiliated with Tidbyt Inc. or the Tronbyte project
+
+## What is Starlark?
+
+[Starlark](https://github.com/bazelbuild/starlark) is a Python-like language originally developed by Google for the Bazel build system. Tidbyt adopted Starlark for building LED display apps because it's:
+
+- **Sandboxed**: Apps run in a safe, restricted environment
+- **Simple**: Python-like syntax that's easy to learn
+- **Deterministic**: Apps produce consistent output
+- **Fast**: Compiled and optimized for performance
+

+
+### Rendering Pipeline
+
+1. **User installs app** from the Tronbyte repository via web UI
+2. **Plugin downloads** the `.star` file (and any assets like images/fonts)
+3. **Schema extraction** parses configuration options from the `.star` source
+4. **User configures** the app through the web UI (timezone, location, API keys, etc.)
+5. **Pixlet renders** the app with user config → produces WebP animation
+6. **Frame extraction** decodes WebP → individual PIL Image frames
+7. **Display scaling** adapts 64x32 Tidbyt output to your matrix size
+8. **Rotation** cycles through your installed apps based on schedule
+
+## Getting Started
+
+### 1. Install Pixlet
+
+Pixlet is the rendering engine that executes Starlark apps. The plugin will attempt to use:
+
+1. **Bundled binary** (recommended): Downloaded to `bin/pixlet/pixlet-{platform}-{arch}`
+2. **System installation**: If `pixlet` is available in your PATH
+
+#### Auto-Install via Web UI
+
+Navigate to: **Plugins → Starlark Apps → Status → Install Pixlet**
+
+This runs the bundled installation script which downloads the appropriate binary for your platform.
+
+#### Manual Installation
+
+```bash
+cd /path/to/LEDMatrix
+bash scripts/download_pixlet.sh
+```
+
+Verify installation:
+```bash
+./bin/pixlet/pixlet-linux-amd64 version
+# Pixlet 0.50.2 (or later)
+```
+
+### 2. Enable the Starlark Apps Plugin
+
+1. Open the web UI
+2. Navigate to **Plugins**
+3. Find **Starlark Apps** in the installed plugins list
+4. Enable the plugin
+5. Configure settings:
+   - **Magnify**: Auto-calculated based on your display size (or set manually)
+   - **Render Interval**: How often apps re-render (default: 300s)
+   - **Display Duration**: How long each app shows (default: 15s)
+   - **Cache Output**: Enable to reduce re-rendering (recommended)
+
+### 3. Browse and Install Apps
+
+1. Navigate to **Plugins → Starlark Apps → App Store**
+2. Browse available apps (974+ options)
+3. Filter by category: Weather, Sports, Finance, Games, Clocks, etc.
+4. Click **Install** on desired apps
+5. Configure each app:
+   - Set location/timezone
+   - Enter API keys if required
+   - Customize display preferences
+
+### 4. Configure Apps
+
+Each app may have different configuration options:
+
+#### Common Configuration Types
+
+- **Location** (lat/lng/timezone): For weather, clocks, transit
+- **API Keys**: For services like weather, stocks, sports scores
+- **Display Preferences**: Colors, units, layouts
+- **Dropdown Options**: Team selections, language, themes
+- **Toggles**: Enable/disable features
+
+Configuration is stored in `starlark-apps/{app-id}/config.json` and persists across app updates.
+
+## App Sources and Categories

+
+## Display Size Compatibility
+
+Tronbyte/Tidbyt apps are designed for **64×32 displays**. LEDMatrix automatically adapts content for different display sizes:
+
+### Magnification
+
+The plugin calculates optimal magnification based on your display:
+
+```text
+magnify = floor(min(display_width / 64, display_height / 32))
+```
+
+Examples:
+- **64×32**: magnify = 1 (native, pixel-perfect)
+- **128×64**: magnify = 2 (2x scaling, crisp)
+- **192×64**: magnify = 2 (2x + horizontal centering)
+- **256×64**: magnify = 2 (2x + centering)
+
+### Scaling Modes
+
+**Config → Starlark Apps → Scale Method:**
+- `nearest` (default): Sharp pixels, retro look
+- `bilinear`: Smooth scaling, slight blur
+- `bicubic`: Higher quality smooth scaling
+- `lanczos`: Best quality, most processing
+
+**Center vs Scale:**
+- `scale_output=true`: Stretch to fill display (may distort aspect ratio)
+- `center_small_output=true`: Center output without stretching (preserves aspect ratio)
+
+## Configuration Schema Extraction
+
+LEDMatrix automatically extracts configuration schemas from Starlark apps by parsing the `get_schema()` function in the `.star` source code.
+
+### Supported Field Types
+
+| Starlark Type | Web UI Rendering |
+|--------------|------------------|
+| `schema.Location` | Lat/Lng/Timezone picker |
+| `schema.Text` | Text input field |
+| `schema.Toggle` | Checkbox/switch |
+| `schema.Dropdown` | Select dropdown |
+| `schema.Color` | Color picker |
+| `schema.DateTime` | Date/time picker |
+| `schema.OAuth2` | Warning message (not supported) |
+| `schema.PhotoSelect` | Warning message (not supported) |
+| `schema.LocationBased` | Text fallback with note |
+| `schema.Typeahead` | Text fallback with note |
+
+### Schema Coverage
+
+- **90-95%** of apps: Full schema support
+- **5%**: Partial extraction (complex/dynamic schemas)
+- **<1%**: No schema (apps without configuration)
+
+Apps without extracted schemas can still run with default settings.

+
+## API Keys and External Services
+
+Many apps require API keys for external services:
+
+### Common API Services
+
+- **Weather**: OpenWeatherMap, Weather.gov, Dark Sky
+- **Sports**: ESPN, The Sports DB, SportsData.io
+- **Finance**: Alpha Vantage, CoinGecko, Yahoo Finance
+- **Transit**: TransitLand, NextBus, local transit APIs
+- **News**: NewsAPI, Reddit, RSS feeds
+
+### Security Note
+
+- API keys are stored in `config.json` files on disk
+- The LEDMatrix web interface does NOT encrypt API keys
+- Ensure your Raspberry Pi is on a trusted network
+- Use read-only or limited-scope API keys when possible
+- **Never commit `starlark-apps/*/config.json` to version control**
+
+## Troubleshooting
+
+### Pixlet Not Found
+
+**Symptom**: "Pixlet binary not found" error
+
+**Solutions**:
+1. Run auto-installer: **Plugins → Starlark Apps → Install Pixlet**
+2. Manual install: `bash scripts/download_pixlet.sh`
+3. Check permissions: `chmod +x bin/pixlet/pixlet-*`
+4. Verify architecture: `uname -m` matches binary name
+
+### App Fails to Render
+
+**Symptom**: "Rendering failed" error in logs
+
+**Solutions**:
+1. Check logs: `journalctl -u ledmatrix | grep -i pixlet`
+2. Verify config: Ensure all required fields are filled
+3. Test manually: `./bin/pixlet/pixlet-linux-amd64 render starlark-apps/{app-id}/{app-id}.star`
+4. Missing assets: Some apps need images/fonts that may fail to download
+5. API issues: Check API keys and rate limits
+
+### Schema Not Extracted
+
+**Symptom**: App installs but shows no configuration options
+
+**Solutions**:
+1. App may not have a `get_schema()` function (normal for some apps)
+2. Schema extraction failed: Check logs for parse errors
+3. Manual config: Edit `starlark-apps/{app-id}/config.json` directly
+4. Report issue: File bug with app details at LEDMatrix GitHub
+
+### Apps Show Distorted/Wrong Size
+
+**Symptom**: Content appears stretched, squished, or cropped
+
+**Solutions**:
+1. Check magnify setting: **Plugins → Starlark Apps → Config**
+2. Try `center_small_output=true` to preserve aspect ratio
+3. Adjust `magnify` manually (1-8) for your display size
+4. Some apps assume 64×32 - may not scale perfectly to all sizes
+
+### App Shows Outdated Data
+
+**Symptom**: Weather, sports scores, etc. don't update
+
+**Solutions**:
+1. Check render interval: **App Config → Render Interval** (300s default)
+2. Force re-render: **Plugins → Starlark Apps → {App} → Render Now**
+3. Clear cache: Restart LEDMatrix service
+4. API rate limits: Some services throttle requests
+5. Check app logs for API errors
+
+## Performance Considerations
+
+### Render Intervals
+
+- Apps re-render on a schedule (default: 300s = 5 minutes)
+- Lower intervals = more CPU/API usage
+- Recommended minimums:
+  - Static content (clocks): 30-60s
+  - Weather: 300s (5min)
+  - Sports scores: 60-120s
+  - Stock tickers: 60s
+
+### Caching
+
+Enable caching to reduce CPU load:
+- `cache_rendered_output=true` (recommended)
+- `cache_ttl=300` (5 minutes)
+
+Cached WebP files are stored in `starlark-apps/{app-id}/cached_render.webp`
+
+### Display Rotation
+
+Balance number of enabled apps with display duration:
+- 5 apps × 15s = 75s full cycle
+- 20 apps × 15s = 300s (5 min) cycle
+
+Long cycles may cause apps to render before being displayed.
+
+## Limitations
+
+### Unsupported Features
+
+- **OAuth2 Authentication**: Apps requiring OAuth login won't work
+- **PhotoSelect**: Image upload from mobile device not supported
+- **Push Notifications**: Apps can't receive real-time events
+- **Background Jobs**: No persistent background tasks
+
+### API Rate Limits
+
+Many apps use free API tiers with rate limits:
+- Rendering too frequently may exceed limits
+- Use appropriate `render_interval` settings
+- Consider paid API tiers for heavy usage
+
+### Display Size Constraints
+
+Apps designed for 64×32 may not utilize larger displays fully:
+- Content may appear small on 128×64+ displays
+- Magnification helps but doesn't add detail
+- Some apps hard-code 64×32 dimensions
+
+## Advanced Usage
+
+### Manual App Installation
+
+Upload custom `.star` files:
+1. Navigate to **Starlark Apps → Upload**
+2. Select `.star` file from disk
+3. Configure app ID and metadata
+4. Set render/display timing
+
+### Custom App Development
+
+While LEDMatrix runs Tronbyte apps, you can also create your own:
+
+1. **Learn Starlark**: [Tidbyt Developer Docs](https://tidbyt.dev/)
+2. **Write `.star` file**: Use Pixlet APIs for rendering
+3. **Test locally**: `pixlet render myapp.star`
+4. **Upload**: Use LEDMatrix web UI to install
+5. **Share**: Contribute to [Tronbyte Apps](https://github.com/tronbyt/apps) repo
+
+### Configuration Reference
+
+**Plugin Config** (`config/config.json` → `plugins.starlark-apps`):
+
+```json
+{
+  "enabled": true,
+  "magnify": 0,                    // 0 = auto, 1-8 = manual
+  "render_timeout": 30,            // Max seconds for Pixlet render
+  "cache_rendered_output": true,   // Cache WebP files
+  "cache_ttl": 300,                // Cache duration (seconds)
+  "scale_output": true,            // Scale to display size
+  "scale_method": "nearest",       // nearest|bilinear|bicubic|lanczos
+  "center_small_output": false,    // Center instead of scale
+  "default_frame_delay": 50,       // Frame timing (ms)
+  "max_frames": null,              // Limit frames (null = unlimited)
+  "auto_refresh_apps": true        // Auto re-render on interval
+}
+```
+
+**App Config** (`starlark-apps/{app-id}/config.json`):
+
+```json
+{
+  "location": "{\"lat\":\"40.7128\",\"lng\":\"-74.0060\",\"timezone\":\"America/New_York\"}",
+  "units": "imperial",
+  "api_key": "your-api-key-here",
+  "render_interval": 300,          // App-specific override
+  "display_duration": 15           // App-specific override
+}

+# Troubleshooting Guide
+
+## Quick Diagnosis Steps
+
+Run these checks first to quickly identify common issues:
+
+### 1. Check Service Status
+
+```bash
+# Check all LEDMatrix services
+sudo systemctl status ledmatrix
+sudo systemctl status ledmatrix-web
+sudo systemctl status ledmatrix-wifi-monitor
+
+# Check AP mode services (if using WiFi)
+sudo systemctl status hostapd
+sudo systemctl status dnsmasq
+```
+
+**Note:** Look for `active (running)` status and check for error messages in the output.
+
+### 2. View Service Logs
+
+**IMPORTANT:** The web service logs to **syslog**, NOT stdout. Use `journalctl` to view logs:
+
+```bash
+# View all recent logs
+sudo journalctl -u ledmatrix -n 50
+sudo journalctl -u ledmatrix-web -n 50
+
+# Follow logs in real-time
+sudo journalctl -u ledmatrix -f
+
+# View logs from last hour
+sudo journalctl -u ledmatrix-web --since "1 hour ago"
+
+# Filter for errors only
+sudo journalctl -u ledmatrix -p err
+```
+
+### 3. Run Diagnostic Scripts
+
+```bash
+# Web interface diagnostics
+bash scripts/diagnose_web_interface.sh
+
+# WiFi setup verification
+./scripts/verify_wifi_setup.sh
+
+# Captive portal troubleshooting
+./scripts/troubleshoot_captive_portal.sh
+```
+
+> Weather is provided by the `ledmatrix-weather` plugin (installed via the
+> Plugin Store). To troubleshoot weather, check that plugin's tab in the
+> web UI for its API key and recent error messages, then watch the
+> **Logs** tab.
+
+### 4. Check Configuration
+
+```bash
+# Verify web interface autostart
+cat config/config.json | grep web_display_autostart
+
+# Check plugin enabled status
+cat config/config.json | grep -A 2 "plugin-id"
+
+# Verify API keys present
+ls -l config/config_secrets.json
+```
+
+### 5. Test Manual Startup
+
+```bash
+# Test web interface manually
+python3 web_interface/start.py
+
+# If it works manually but not as a service, check systemd service file
+```
+
+---
+
+## Common Issues by Category

+   ls -l web_interface/blueprints/api_v3.py
+   ls -l web_interface/blueprints/pages_v3.py
+   ```
+
+2. **Check for __init__.py files:**
+   ```bash
+   ls -l web_interface/__init__.py
+   ls -l web_interface/blueprints/__init__.py
+   ```
+
+3. **Test import manually:**
+   ```bash
+   cd /home/ledpi/LEDMatrix
+   python3 -c "from web_interface.app import app"
+   ```
+
+---
+
+### WiFi & AP Mode Issues
+
+#### AP Mode Not Activating
+
+**Symptoms:**
+- WiFi disconnected but AP mode doesn't start
+- Cannot find "LEDMatrix-Setup" network
+
+**Solutions:**
+
+1. **Check auto-enable setting:**
+   ```bash
+   cat config/wifi_config.json | grep auto_enable_ap_mode
+   # Should show: "auto_enable_ap_mode": true
+   ```
+
+2. **Verify WiFi monitor service is running:**
+   ```bash
+   sudo systemctl status ledmatrix-wifi-monitor
+   ```
+
+3. **Wait for grace period (90 seconds):**
+   - AP mode requires 3 consecutive disconnected checks at 30-second intervals
+   - Total wait time: 90 seconds after WiFi disconnects
+
+4. **Check if Ethernet is connected:**
+   ```bash
+   nmcli device status
+   # If Ethernet is connected, AP mode won't activate
+   ```
+
+5. **Check required services:**
+   ```bash
+   sudo systemctl status hostapd
+   sudo systemctl status dnsmasq
+   ```
+
+6. **Manually enable AP mode:**
+   ```bash
+   # Via API
+   curl -X POST http://localhost:5000/api/wifi/ap/enable
+
+   # Via Python
+   python3 -c "
+   from src.wifi_manager import WiFiManager
+   wm = WiFiManager()
+   wm.enable_ap_mode()
+   "
+   ```
+
+#### Cannot Connect to AP Mode / Connection Refused
+
+**Symptoms:**
+- Can see "LEDMatrix-Setup" network but can't connect to web interface
+- Browser shows "Connection Refused" or "Can't connect to server"
+- AP mode active but web interface not accessible
+
+**Solutions:**
+
+1. **Verify web server is running:**
+   ```bash
+   sudo systemctl status ledmatrix-web
+   # Should be active (running)
+   ```
+
+2. **Use correct IP address and port:**
+   - Correct: `http://192.168.4.1:5000`
+   - NOT: `http://192.168.4.1` (port 80 — nothing listens there)
+
+3. **Check wlan0 has correct IP:**
+   ```bash
+   ip addr show wlan0
+   # Should show: inet 192.168.4.1/24
+   ```
+
+4. **Verify hostapd and dnsmasq are running:**
+   ```bash
+   sudo systemctl status hostapd
+   sudo systemctl status dnsmasq
+   ```
+
+5. **Test from the Pi itself:**
+   ```bash
+   curl http://192.168.4.1:5000
+   # Should return HTML
+   ```
+
+#### DNS Resolution Failures
+
+**Symptoms:**
+- Captive portal doesn't redirect automatically
+- DNS lookups fail when connected to AP mode
+
+**Solutions:**
+
+1. **Check dnsmasq status:**
+   ```bash
+   sudo systemctl status dnsmasq
+   sudo journalctl -u dnsmasq -n 20
+   ```
+
+2. **Verify DNS configuration:**
+   ```bash
+   cat /etc/dnsmasq.conf | grep -v "^#" | grep -v "^$"
+   ```
+
+3. **Test DNS resolution:**
+   ```bash
+   nslookup captive.apple.com
+   # Should resolve to 192.168.4.1 when in AP mode
+   ```
+
+4. **Manual captive portal testing:**
+   - Try these URLs manually:
+     - `http://192.168.4.1:5000`
+     - `http://captive.apple.com`
+     - `http://connectivitycheck.gstatic.com/generate_204`
+
+#### Firewall Blocking Port 5000
+
+**Symptoms:**
+- Services running but cannot connect
+- Works from Pi but not from other devices
+
+**Solutions:**
+
+1. **Check UFW status:**
+   ```bash
+   sudo ufw status
+   ```
+
+2. **Allow port 5000:**
+   ```bash
+   sudo ufw allow 5000/tcp
+   ```
+
+3. **Check iptables:**
+   ```bash
+   sudo iptables -L -n
+   ```
+
+4. **Temporarily disable firewall to test:**
+   ```bash
+   sudo ufw disable
+   # Test if it works, then re-enable and add rule
+   sudo ufw enable
+   sudo ufw allow 5000/tcp
+   ```
+

+   ```
+
+3. **Check dependencies installed:**
+   ```bash
+   if [ -f plugins/plugin-id/requirements.txt ]; then
+     pip3 install --break-system-packages -r plugins/plugin-id/requirements.txt
+   fi
+   ```
+
+4. **Check logs for plugin errors:**
+   ```bash
+   sudo journalctl -u ledmatrix -f | grep plugin-id
+   ```
+
+5. **Test plugin import:**

+     "ledmatrix-weather": {
+       "update_interval": 300,
+       ...
+     }
+   }
+   ```
+   **Note:** Minimum recommended: 300 seconds (5 minutes)
+
+2. **Check current rate limit usage:**
+   - OpenWeatherMap free tier: 1,000 calls/day, 60 calls/minute
+   - With 300s interval: 288 calls/day (well within limits)
+
+3. **Monitor API calls:**
+   ```bash
+   sudo journalctl -u ledmatrix -f | grep "openweathermap"
+   ```
+
+#### Invalid Location Configuration
+
+**Symptoms:**
+- "No Weather Data" message
+- Logs show location not found errors
+
+**Solutions:**
+
+1. **Use correct location format:**

+       "city": "Tampa",
+       "state": "FL",
+       "country": "US"
+     }
+   }
+   ```
+
+2. **Use ISO country codes:**
+   - US = United States
+   - GB = United Kingdom
+   - CA = Canada
+   - etc.
+
+3. **Test API call manually:**
+   ```bash
+   API_KEY="your-key-here"
+   curl "http://api.openweathermap.org/data/2.5/weather?q=Tampa,FL,US&appid=${API_KEY}"
+   ```
+
+#### Network Connectivity to OpenWeatherMap
+
+**Symptoms:**

+# Web Interface Guide
+
+## Overview
+
+The LEDMatrix web interface provides a complete control panel for managing your LED matrix display. Access all features through a modern, responsive web interface that works on desktop, tablet, and mobile devices.
+
+---
+
+## Quick Start
+
+### Accessing the Interface
+
+1. Find your Raspberry Pi's IP address:
+   ```bash
+   hostname -I
+   ```
+
+2. Open a web browser and navigate to:
+   ```
+   http://your-pi-ip:5000
+   ```
+
+3. The interface will load with the Overview tab displaying system stats and a live display preview.
+
+**Note:** If the interface doesn't load, verify the web service is running:
+```bash
+sudo systemctl status ledmatrix-web
+```
+
+---
+
+## Navigation
+
+The interface uses a two-row tab layout. The system tabs are always
+present:
+
+- **Overview** — System stats, quick actions, live display preview
+- **General** — Timezone, location, plugin-system settings
+- **WiFi** — Network selection and AP-mode setup
+- **Schedule** — Power and dim schedules
+- **Display** — Matrix hardware configuration (rows, cols, hardware
+  mapping, GPIO slowdown, brightness, PWM)
+- **Config Editor** — Raw `config.json` editor with validation
+- **Fonts** — Upload and manage fonts
+- **Logs** — Real-time log streaming
+- **Cache** — Cached data inspection and cleanup
+- **Operation History** — Recent service operations
+
+A second nav row holds plugin tabs:
+
+- **Plugin Manager** — browse the **Plugin Store** section, install
+  plugins from GitHub, enable/disable installed plugins
+- **<plugin-id>** — one tab per installed plugin for its own
+  configuration form (auto-generated from the plugin's
+  `config_schema.json`)
+
+---
+
+## Features and Usage
+
+### Overview Tab
+
+The Overview tab provides at-a-glance information and quick actions:
+
+**System Stats:**
+- CPU usage and temperature
+- Memory usage
+- Disk usage
+- Network status
+
+**Quick Actions** (verified in `web_interface/templates/v3/partials/overview.html`):
+- **Start Display** / **Stop Display** — control the display service
+- **Restart Display Service** — apply configuration changes
+- **Restart Web Service** — restart the web UI itself
+- **Update Code** — `git pull` the latest version (stashes local changes)
+- **Reboot System** / **Shutdown System** — confirm-gated power controls
+
+**Display Preview:**
+- Live preview of what's currently shown on the LED matrix
+- Updates in real-time
+- Useful for remote monitoring
+
+### General Tab
+
+Configure basic system settings:
+
+- **Timezone** — used by all time/date displays
+- **Location** — city/state/country for weather and other location-aware
+  plugins
+- **Plugin System Settings** — including the `plugins_directory` (default
+  `plugin-repos/`) used by the plugin loader
+- **Autostart** options for the display service
+
+Click **Save** to write changes to `config/config.json`. Most changes
+require a display service restart from **Overview**.
+
+### Display Tab
+
+Configure your LED matrix hardware:
+
+**Matrix configuration:**
+- `rows` — LED rows (typically 32 or 64)
+- `cols` — LED columns (typically 64 or 96)
+- `chain_length` — number of horizontally chained panels
+- `parallel` — number of parallel chains
+- `hardware_mapping` — `adafruit-hat-pwm` (with PWM jumper mod),
+  `adafruit-hat` (without), `regular`, or `regular-pi1`
+- `gpio_slowdown` — must match your Pi model (3 for Pi 3, 4 for Pi 4, etc.)
+- `brightness` — 0–100%
+- `pwm_bits`, `pwm_lsb_nanoseconds`, `pwm_dither_bits` — PWM tuning
+- Dynamic Duration — global cap for plugins that extend their display
+  time based on content
+
+Changes require **Restart Display Service** from the Overview tab.
+
+### Plugin Manager Tab
+
+The Plugin Manager has three main sections:
+
+1. **Installed Plugins** — toggle installed plugins on/off, see version
+   info. Each installed plugin also gets its own tab in the second nav
+   row for its configuration form.
+2. **Plugin Store** — browse plugins from the official
+   `ledmatrix-plugins` registry. Click **Install** to fetch and
+   install. Filter by category and search.
+3. **Install from GitHub** — install third-party plugins by pasting a
+   GitHub repository URL. **Install Single Plugin** for a single-plugin
+   repo, **Load Registry** for a multi-plugin monorepo.
+
+When a plugin is installed and enabled:
+- A new tab for that plugin appears in the second nav row
+- Open the tab to edit its config (auto-generated form from
+  `config_schema.json`)
+- The tab also exposes **Run On-Demand** / **Stop On-Demand** controls
+  to render that plugin immediately, even if it's disabled in the
+  rotation
+
+### Per-plugin Configuration Tabs
+
+Each installed plugin has its own tab in the second nav row. The form
+fields are auto-generated from the plugin's `config_schema.json`, so
+options always match the plugin's current code.
+
+To temporarily run a plugin outside the normal rotation, use the
+**Run On-Demand** / **Stop On-Demand** buttons inside its tab. This
+works even when the plugin is disabled.
+
+### Fonts Tab
+
+Manage fonts for your display:
+
+**Upload Fonts:**
+- Drag and drop font files (.ttf, .otf, .bdf)
+- Upload multiple files at once
+- Progress indicator shows upload status
+
+**Font Catalog:**
+- View all available fonts
+- See font previews
+- Check font sizes and styles
+
+**Plugin Font Overrides:**
+- Set custom fonts for specific plugins
+- Override default font choices
+- Preview font changes
+
+**Delete Fonts:**
+- Remove unused fonts
+- Free up disk space
+
+### Logs Tab
+
+View real-time system logs:
+
+**Log Viewer:**
+- Streaming logs from the display service
+- Auto-scroll to latest entries
+- Timestamps for each log entry
+
+**Filtering:**
+- Filter by log level (INFO, WARNING, ERROR)
+- Search for specific text
+- Filter by plugin or component
+
+**Actions:**
+- **Clear**: Clear the current view
+- **Download**: Download logs for offline analysis
+- **Pause**: Pause auto-scrolling
+
+---
+
+## Common Tasks

+5. Click **Restart Display Service** on **Overview**
+
+### Configuring a Plugin
+
+1. Open the plugin's tab in the second nav row (each installed plugin
+   has its own tab)
+2. Edit the auto-generated form
+3. Click **Save**
+4. Restart the display service from **Overview**
+
+### Setting Favorite Sports Teams
+
+Sports favorites live in the relevant plugin's tab — there is no
+separate "Sports Configuration" tab. For example:
+
+1. Install **Hockey Scoreboard** from **Plugin Manager → Plugin Store**
+2. Open the **Hockey Scoreboard** tab in the second nav row
+3. Add your favorites under `favorite_teams.<league>` (e.g.
+   `favorite_teams.nhl`)
+4. Click **Save** and restart the display service
+
+### Troubleshooting Display Issues
+
+1. Navigate to the **Logs** tab
+2. Look for ERROR or WARNING messages
+3. Filter by the problematic plugin or component

+- **Ctrl+F**: Search in logs
+
+---
+
+## API Access
+
+The web interface is built on a REST API that you can access programmatically:
+
+**API Base URL:**
+```
+http://your-pi-ip:5000/api/v3
+```
+
+The API blueprint mounts at `/api/v3` (see
+`web_interface/app.py:144`). All endpoints below are relative to that
+base.
+
+**Common Endpoints:**
+- `GET /api/v3/config/main` — Get main configuration
+- `POST /api/v3/config/main` — Update main configuration
+- `GET /api/v3/system/status` — Get system status
+- `POST /api/v3/system/action` — Control display (start/stop/restart, reboot, etc.)
+- `GET /api/v3/plugins/installed` — List installed plugins
+- `POST /api/v3/plugins/install` — Install a plugin from the store
+- `POST /api/v3/plugins/install-from-url` — Install a plugin from a GitHub URL
+
+**Note:** See [REST_API_REFERENCE.md](REST_API_REFERENCE.md) for complete API documentation.

+      "saved_at": 1234567890.0
+    }
+  ]
+}
+```
+
+### Configuration Options
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `ap_ssid` | `LEDMatrix-Setup` | Network name broadcast in AP mode |
+| `ap_password` | `ledmatrix123` | AP password. Set to `""` to make the network open (no password). |
+| `ap_channel` | `7` | WiFi channel (1, 6, or 11 are non-overlapping) |
+| `auto_enable_ap_mode` | `true` | Automatically enable AP mode when both WiFi and Ethernet are disconnected |
+| `saved_networks` | `[]` | Array of saved WiFi credentials |
+
+### Auto-Enable AP Mode Behavior
+
+**When enabled (`true` - recommended):**
+- AP mode activates automatically after 90-second grace period
+- Only when both WiFi AND Ethernet are disconnected
+- Automatically disables when either WiFi or Ethernet connects
+- Best for portable devices or unreliable network environments
+
+**When disabled (`false`):**
+- AP mode must be manually enabled through web interface
+- Prevents unnecessary AP activation
+- Best for devices with stable network connections
+
+---
+
+## Using WiFi Setup
+
+### Connecting to a WiFi Network
+
+**Via Web Interface:**
+1. Navigate to the **WiFi** tab
+2. Click **Scan** to search for networks
+3. Select a network from the dropdown (or enter SSID manually)
+4. Enter the WiFi password (leave empty for open networks)
+5. Click **Connect**
+6. System will attempt connection
+7. AP mode automatically disables once connected
+
+**Via API:**
+```bash
+# Scan for networks
+curl "http://your-pi-ip:5000/api/v3/wifi/scan"
+
+# Connect to network
+curl -X POST http://your-pi-ip:5000/api/v3/wifi/connect \
+  -H "Content-Type: application/json" \
+  -d '{"ssid": "YourNetwork", "password": "your-password"}'
+```
+
+### Manual AP Mode Control
+
+**Via Web Interface:**
+- **Enable AP Mode**: Click "Enable AP Mode" button (only when WiFi/Ethernet disconnected)
+- **Disable AP Mode**: Click "Disable AP Mode" button (when AP is active)
+
+**Via API:**
+```bash
+# Enable AP mode
+curl -X POST http://your-pi-ip:5000/api/v3/wifi/ap/enable
+
+# Disable AP mode
+curl -X POST http://your-pi-ip:5000/api/v3/wifi/ap/disable
+```
+
+**Note:** Manual enable still requires both WiFi and Ethernet to be disconnected.
+
+---
+
+## Understanding AP Mode Failover
+
+### How the Grace Period Works
+
+The system uses a **grace period mechanism** to prevent false positives from temporary network hiccups:
+
+```
+Check Interval: 30 seconds (default)
+Required Checks: 3 consecutive
+Grace Period: 90 seconds total
+```
+
+**Timeline Example:**
+```
+Time 0s:   WiFi disconnects
+Time 30s:  Check 1 - Disconnected (counter = 1)
+Time 60s:  Check 2 - Disconnected (counter = 2)
+Time 90s:  Check 3 - Disconnected (counter = 3) → AP MODE ENABLED
+```
+
+If WiFi or Ethernet reconnects at any point, the counter resets to 0.
+
+### Why Grace Period is Important
+
+Without a grace period, AP mode would activate during:
+- Brief network hiccups
+- Router reboots
+- Temporary signal interference
+- NetworkManager reconnection attempts
+
+The 90-second grace period ensures AP mode only activates during **sustained disconnection**.
+
+### Connection Priority
+
+The system checks connections in this order:
+1. **WiFi Connection** (highest priority)
+2. **Ethernet Connection** (fallback)
+3. **AP Mode** (last resort - only when both WiFi and Ethernet disconnected)
+
+### Behavior Summary
+
+| WiFi Status | Ethernet Status | Auto-Enable | AP Mode Behavior |
+|-------------|-----------------|-------------|------------------|
+| Any | Any | `false` | Manual enable only |
+| Connected | Any | `true` | Disabled |
+| Disconnected | Connected | `true` | Disabled (Ethernet available) |
+| Disconnected | Disconnected | `true` | Auto-enabled after 90s |
+
+---
+
+## Access Point Configuration
+
+### AP Mode Settings
+
+- **SSID**: `LEDMatrix-Setup` (configurable via `ap_ssid`)
+- **Network**: WPA2, default password `ledmatrix123` (configurable via
+  `ap_password` — set to `""` for an open network)
+- **IP Address**: 192.168.4.1
+- **DHCP Range**: 192.168.4.2 – 192.168.4.20
+- **Channel**: 7 (configurable via `ap_channel`)
+
+### Accessing Services in AP Mode
+
+When AP mode is active:
+- Web Interface: `http://192.168.4.1:5000`
+- SSH: `ssh ledpi@192.168.4.1`
+- Captive portal may automatically redirect browsers
+
+---
+
+## Best Practices
+
+### Security Recommendations
+
+**1. Change AP Password (Optional):**
+```json
+{
+  "ap_password": "your-strong-password"
+}
+```
+
+**Note:** The default password is `ledmatrix123` for easy initial
+setup. Change it for any deployment in a public area, or set
+`ap_password` to `""` if you specifically want an open network.
+
+**2. Use Non-Overlapping WiFi Channels:**
+- Channels 1, 6, 11 are non-overlapping (2.4GHz)
+- Choose a channel that doesn't conflict with your primary network
+- Example: If primary uses channel 1, use channel 11 for AP mode
+
+**3. Secure WiFi Credentials:**
+```bash
+sudo chmod 600 config/wifi_config.json
+```
+
+### Network Configuration Tips
+
+**Save Multiple Networks:**
+```json
+{
+  "saved_networks": [
+    {
+      "ssid": "Home-Network",
+      "password": "home-password"
+    },
+    {
+      "ssid": "Office-Network",
+      "password": "office-password"
+    }
+  ]
+}
+```
+
+**Adjust Check Interval:**
+
+Edit the systemd service file to change grace period:
+```bash
+sudo systemctl edit ledmatrix-wifi-monitor
+```
+
+Add:
+```ini
+[Service]
+ExecStart=
+ExecStart=/usr/bin/python3 /path/to/LEDMatrix/scripts/utils/wifi_monitor_daemon.py --interval 20
+```
+
+**Note:** Interval affects grace period:
+- 20-second interval = 60-second grace period (3 × 20)
+- 30-second interval = 90-second grace period (3 × 30) ← Default
+- 60-second interval = 180-second grace period (3 × 60)
+
+---
+
+## Configuration Scenarios
+
+### Scenario 1: Portable Device with Auto-Failover (Recommended)
+
+**Use Case:** Device may lose WiFi connection
+
+**Configuration:**
+```json
+{
+  "auto_enable_ap_mode": true
+}
+```
+
+**Behavior:**
+- AP mode activates automatically after 90 seconds of disconnection
+- Always provides a way to connect
+- Best for devices that move or have unreliable WiFi
+
+### Scenario 2: Stable Network Connection
+
+**Use Case:** Ethernet or reliable WiFi connection
+
+**Configuration:**
+```json
+{
+  "auto_enable_ap_mode": false
+}
+```
+
+**Behavior:**
+- AP mode must be manually enabled
+- Prevents unnecessary activation
+- Best for stationary devices with stable connections
+
+### Scenario 3: Ethernet Primary with WiFi Backup
+
+**Use Case:** Primary Ethernet, WiFi as backup
+
+**Configuration:**
+```json
+{
+  "auto_enable_ap_mode": true
+}
+```
+
+**Behavior:**
+- Ethernet connection prevents AP mode activation
+- If Ethernet disconnects, WiFi is attempted
+- If both disconnect, AP mode activates after grace period
+- Best for devices with both Ethernet and WiFi
+
+---
+
+## Troubleshooting
+
+### AP Mode Not Activating
+
+**Check 1: Auto-Enable Setting**
+```bash
+cat config/wifi_config.json | grep auto_enable_ap_mode
+```
+Should show `"auto_enable_ap_mode": true`
+
+**Check 2: Service Status**
+```bash
+sudo systemctl status ledmatrix-wifi-monitor
+```
+Service should be `active (running)`
+
+**Check 3: Grace Period**
+- Wait at least 90 seconds after disconnection
+- Check logs: `sudo journalctl -u ledmatrix-wifi-monitor -f`
+
+**Check 4: Ethernet Connection**
+- If Ethernet is connected, AP mode won't activate
+- Verify: `nmcli device status`
+- Disconnect Ethernet to test AP mode
+
+**Check 5: Required Packages**
+```bash
+# Verify hostapd is installed
+which hostapd
+
+# Verify dnsmasq is installed
+which dnsmasq
+```
+
+### Cannot Access AP Mode
+
+**Check 1: AP Mode Active**
+```bash
+sudo systemctl status hostapd
+sudo systemctl status dnsmasq
+```
+Both should be running
+
+**Check 2: Network Interface**
+```bash
+ip addr show wlan0
+```
+Should show IP `192.168.4.1`
+
+**Check 3: WiFi Interface Available**
+```bash
+ip link show wlan0
+```
+Interface should exist
+
+**Check 4: Try Manual Enable**
+- Use web interface: WiFi tab → Enable AP Mode
+- Or via API: `curl -X POST http://localhost:5000/api/v3/wifi/ap/enable`
+
+### Cannot Connect to WiFi Network
+
+**Check 1: Verify Credentials**
+- Ensure SSID and password are correct
+- Check for hidden networks (manual SSID entry required)
+
+**Check 2: Check Logs**
+```bash
+# WiFi monitor logs
+sudo journalctl -u ledmatrix-wifi-monitor -f
+
+# NetworkManager logs
+sudo journalctl -u NetworkManager -n 50
+```
+
+**Check 3: Network Compatibility**
+- Verify network is 2.4GHz (5GHz may not be supported on all Pi models)
+- Check if network requires special authentication
+
+### AP Mode Not Disabling After WiFi Connect
+
+**Check 1: WiFi Connection Status**
+```bash
+nmcli device status
+```
+
+**Check 2: Manually Disable**
+- Use web interface: WiFi tab → Disable AP Mode
+- Or restart service: `sudo systemctl restart ledmatrix-wifi-monitor`
+
+**Check 3: Check Logs**
+```bash
+sudo journalctl -u ledmatrix-wifi-monitor -n 50
+```
+
+### AP Mode Activating Unexpectedly
+
+**Check 1: Network Stability**
+- Verify WiFi connection is stable
+- Check router status
+- Check signal strength
+
+**Check 2: Disable Auto-Enable**
+```bash
+nano config/wifi_config.json
+# Change: "auto_enable_ap_mode": false
+sudo systemctl restart ledmatrix-wifi-monitor
+```
+
+**Check 3: Increase Grace Period**
+- Edit service file to increase check interval
+- Longer interval = longer grace period
+- See "Best Practices" section above
+
+---
+
+## Monitoring and Diagnostics
+
+### Check WiFi Status
+
+**Via Python:**
+```python
+from src.wifi_manager import WiFiManager
+
+wm = WiFiManager()
+status = wm.get_wifi_status()

+
+## Technical Details
+
+### WiFi Monitor Daemon
+
+The WiFi monitor daemon (`wifi_monitor_daemon.py`) runs as a background service that:
+
+1. Checks WiFi and Ethernet connection status every 30 seconds (configurable)
+2. Maintains disconnected check counter for grace period
+3. Automatically enables AP mode when:
+   - `auto_enable_ap_mode` is enabled AND
+   - Both WiFi and Ethernet disconnected AND
+   - Grace period elapsed (3 consecutive checks)
+4. Automatically disables AP mode when WiFi or Ethernet connects
+5. Logs all state changes
+
+### WiFi Detection Methods
+
+The WiFi manager tries multiple methods:
+
+1. **NetworkManager (nmcli)** - Preferred method
+2. **iwconfig** - Fallback for systems without NetworkManager
+
+### Network Scanning Methods
+
+1. **nmcli** - Fast, preferred method
+2. **iwlist** - Fallback for older systems
+
+### Access Point Implementation
+
+- Uses `hostapd` for WiFi access point functionality
+- Uses `dnsmasq` for DHCP and DNS services
+- Configures wlan0 interface with IP 192.168.4.1
+- Provides DHCP range: 192.168.4.2-20
+- Captive portal with DNS redirection

+# Vegas Scroll Mode - Plugin Developer Guide
+
+Vegas scroll mode displays content from multiple plugins in a continuous horizontal scroll, similar to the news tickers seen in Las Vegas casinos. This guide explains how to integrate your plugin with Vegas mode.
+
+## Overview
+
+When Vegas mode is enabled, the display controller composes content from all enabled plugins into a single continuous scroll. Each plugin can control how its content appears in the scroll using one of three **display modes**:
+
+| Mode | Behavior | Best For |
+|------|----------|----------|
+| **SCROLL** | Content scrolls continuously within the stream | Multi-item plugins (sports scores, odds, news) |
+| **FIXED_SEGMENT** | Fixed-width block that scrolls by | Static info (clock, weather, current temp) |
+| **STATIC** | Scroll pauses, plugin displays for duration, then resumes | Important alerts, detailed views |
+
+## Quick Start
+
+### Minimal Integration (Zero Code Changes)
+
+If you do nothing, your plugin will work with Vegas mode using these defaults:
+
+- Plugins with `get_vegas_content_type() == 'multi'` use **SCROLL** mode
+- Plugins with `get_vegas_content_type() == 'static'` use **FIXED_SEGMENT** mode
+- Content is captured by calling your plugin's `display()` method
+
+### Basic Integration
+
+To provide optimized Vegas content, implement `get_vegas_content()`:
+
+```python
+from PIL import Image
+
+class MyPlugin(BasePlugin):
+    def get_vegas_content(self):
+        """Return content for Vegas scroll mode."""
+        # Return a single image for fixed content
+        return self._render_current_view()
+
+        # OR return multiple images for multi-item content
+        # return [self._render_item(item) for item in self.items]
+```
+
+### Full Integration
+
+For complete control over Vegas behavior, implement these methods:
+
+```python
+from src.plugin_system.base_plugin import BasePlugin, VegasDisplayMode
+
+class MyPlugin(BasePlugin):
+    def get_vegas_content_type(self) -> str:
+        """Legacy method - determines default mode mapping."""
+        return 'multi'  # or 'static' or 'none'
+
+    def get_vegas_display_mode(self) -> VegasDisplayMode:
+        """Specify how this plugin behaves in Vegas scroll."""
+        return VegasDisplayMode.SCROLL
+
+    def get_supported_vegas_modes(self) -> list:
+        """Return list of modes users can configure."""
+        return [VegasDisplayMode.SCROLL, VegasDisplayMode.FIXED_SEGMENT]
+
+    def get_vegas_content(self):
+        """Return PIL Image(s) for the scroll."""
+        return [self._render_game(g) for g in self.games]
+
+    def get_vegas_segment_width(self) -> int:
+        """For FIXED_SEGMENT: width in panels (optional)."""
+        return 2  # Use 2 panels width
+```
+
+## Display Modes Explained
+
+### SCROLL Mode
+
+Content scrolls continuously within the Vegas stream. Best for plugins with multiple items.
+
+```python
+def get_vegas_display_mode(self):
+    return VegasDisplayMode.SCROLL
+
+def get_vegas_content(self):
+    # Return list of images - each scrolls individually
+    images = []
+    for game in self.games:
+        img = Image.new('RGB', (200, 32))
+        # ... render game info ...
+        images.append(img)
+    return images
+```
+
+**When to use:**
+- Sports scores with multiple games
+- Stock/odds tickers with multiple items
+- News feeds with multiple headlines
+
+### FIXED_SEGMENT Mode
+
+Content is rendered as a fixed-width block that scrolls by with other content.
+
+```python
+def get_vegas_display_mode(self):
+    return VegasDisplayMode.FIXED_SEGMENT
+
+def get_vegas_content(self):
+    # Return single image at your preferred width
+    img = Image.new('RGB', (128, 32))  # 2 panels wide
+    # ... render clock/weather/etc ...
+    return img
+
+def get_vegas_segment_width(self):
+    # Optional: specify width in panels
+    return 2
+```
+
+**When to use:**
+- Clock display
+- Current weather/temperature
+- System status indicators
+- Any "at a glance" information
+
+### STATIC Mode
+
+Scroll pauses completely, your plugin displays using its normal `display()` method for its configured duration, then scroll resumes.
+
+```python
+def get_vegas_display_mode(self):
+    return VegasDisplayMode.STATIC
+
+def get_display_duration(self):
+    # How long to pause and show this plugin
+    return 10.0  # 10 seconds
+```
+
+**When to use:**
+- Important alerts that need attention
+- Detailed information that's hard to read while scrolling
+- Interactive or animated content
+- Content that requires the full display
+
+## User Configuration
+
+Users can override the default display mode per-plugin in their config:
+
+```json
+{
+  "my_plugin": {
+    "enabled": true,
+    "vegas_mode": "static",       // Override: "scroll", "fixed", or "static"
+    "vegas_panel_count": 2,       // Width in panels for fixed mode
+    "display_duration": 10        // Duration for static mode
+  }
+}
+```
+
+The `get_vegas_display_mode()` method checks config first, then falls back to your implementation.
+
+## Content Rendering Guidelines
+
+### Image Dimensions
+
+- **Height**: Must match display height (typically 32 pixels)
+- **Width**:
+  - SCROLL: Any width, content will scroll
+  - FIXED_SEGMENT: `panels × single_panel_width` (e.g., 2 × 64 = 128px)
+
+### Color Mode
+
+Always use RGB mode for images:
+
+```python
+img = Image.new('RGB', (width, 32), color=(0, 0, 0))
+```
+
+### Performance Tips
+
+1. **Cache rendered images** - Don't re-render on every call
+2. **Pre-render on update()** - Render images when data changes, not when Vegas requests them
+3. **Keep images small** - Memory adds up with multiple plugins
+
+```python
+class MyPlugin(BasePlugin):
+    def __init__(self, ...):
+        super().__init__(...)
+        self._cached_vegas_images = None
+        self._cache_valid = False
+
+    def update(self):
+        # Fetch new data
+        self.data = self._fetch_data()
+        # Invalidate cache so next Vegas request re-renders
+        self._cache_valid = False
+
+    def get_vegas_content(self):
+        if not self._cache_valid:
+            self._cached_vegas_images = self._render_all_items()
+            self._cache_valid = True
+        return self._cached_vegas_images
+```
+
+## Fallback Behavior
+
+If your plugin doesn't implement `get_vegas_content()`, Vegas mode will:
+
+1. Create a temporary canvas matching display dimensions
+2. Call your `display()` method
+3. Capture the resulting image
+4. Use that image in the scroll
+
+This works but is less efficient than providing native Vegas content.
+
+## Excluding from Vegas Mode
+
+To exclude your plugin from Vegas scroll entirely:
+
+```python
+def get_vegas_content_type(self):
+    return 'none'
+```
+
+Or users can exclude via config:
+
+```json
+{
+  "display": {
+    "vegas_scroll": {
+      "excluded_plugins": ["my_plugin"]
+    }
+  }
+}
+```
+
+## Complete Example
+
+Here's a complete example of a weather plugin with full Vegas integration:
+
+```python
+from PIL import Image, ImageDraw
+from src.plugin_system.base_plugin import BasePlugin, VegasDisplayMode
+
+class WeatherPlugin(BasePlugin):
+    def __init__(self, *args, **kwargs):
+        super().__init__(*args, **kwargs)
+        self.temperature = None
+        self.conditions = None
+        self._vegas_image = None
+
+    def update(self):
+        """Fetch weather data."""
+        data = self._fetch_weather_api()
+        self.temperature = data['temp']
+        self.conditions = data['conditions']
+        self._vegas_image = None  # Invalidate cache
+
+    def display(self, force_clear=False):
+        """Standard display for normal rotation."""
+        if force_clear:
+            self.display_manager.clear()
+
+        # Full weather display with details
+        self.display_manager.draw_text(
+            f"{self.temperature}°F",
+            x=10, y=8, color=(255, 255, 255)
+        )
+        self.display_manager.draw_text(
+            self.conditions,
+            x=10, y=20, color=(200, 200, 200)
+        )

+## API Reference
+
+### VegasDisplayMode Enum
+
+```python
+from src.plugin_system.base_plugin import VegasDisplayMode
+
+VegasDisplayMode.SCROLL        # "scroll" - continuous scrolling
+VegasDisplayMode.FIXED_SEGMENT # "fixed" - fixed block in scroll
+VegasDisplayMode.STATIC        # "static" - pause scroll to display
+```
+
+### BasePlugin Vegas Methods
+
+| Method | Returns | Description |
+|--------|---------|-------------|
+| `get_vegas_content()` | `Image` or `List[Image]` or `None` | Content for Vegas scroll |
+| `get_vegas_content_type()` | `str` | Legacy: 'multi', 'static', or 'none' |
+| `get_vegas_display_mode()` | `VegasDisplayMode` | How plugin behaves in Vegas |
+| `get_supported_vegas_modes()` | `List[VegasDisplayMode]` | Modes available for user config |
+| `get_vegas_segment_width()` | `int` or `None` | Width in panels for FIXED_SEGMENT |
+
+### Configuration Options
+
+**Per-plugin config:**
+```json
+{
+  "plugin_id": {
+    "vegas_mode": "scroll|fixed|static",
+    "vegas_panel_count": 2,
+    "display_duration": 15
+  }
+}
+```
+
+**Global Vegas config:**
+```json
+{
+  "display": {
+    "vegas_scroll": {
+      "enabled": true,
+      "scroll_speed": 50,
+      "separator_width": 32,
+      "plugin_order": ["clock", "weather", "sports"],
+      "excluded_plugins": ["debug_plugin"],
+      "target_fps": 125,
+      "buffer_ahead": 2
+    }
+  }
+}
+```
+
+## Troubleshooting
+
+### Plugin not appearing in Vegas scroll
+
+1. Check `get_vegas_content_type()` doesn't return `'none'`
+2. Verify plugin is not in `excluded_plugins` list
+3. Ensure plugin is enabled
+
+### Content looks wrong in scroll
+
+1. Verify image height matches display height (32px typical)
+2. Check image mode is 'RGB'
+3. Test with `get_vegas_content()` returning a simple test image
+
+### STATIC mode not pausing
+
+1. Verify `get_vegas_display_mode()` returns `VegasDisplayMode.STATIC`
+2. Check user hasn't overridden with `vegas_mode` in config
+3. Ensure `display()` method works correctly
+
+### Performance issues
+
+1. Implement image caching in `get_vegas_content()`
+2. Pre-render images in `update()` instead of on-demand
+3. Reduce image dimensions if possible
