docs: address CodeRabbit review comments on #306

Reviewed all 12 CodeRabbit comments on PR #306, verified each against
the current code, and fixed the 11 valid ones. The 12th finding is a
real code bug (cache_manager.delete() calls in api_helper.py and
resource_monitor.py) that's already in the planned follow-up code-fix
PR, so it stays out of this docs PR.

Fixed:

.cursor/plugins_guide.md, .cursor/README.md, .cursorrules
- I claimed "there is no --emulator flag" in 3 places. Verified in
  run.py:19-20 that the -e/--emulator flag is defined and functional
  (it sets os.environ["EMULATOR"]="true" before the display imports).
  Other docs I didn't touch (.cursor/plugin_templates/QUICK_START.md,
  docs/PLUGIN_DEVELOPMENT_GUIDE.md) already use the flag correctly.
  Replaced all 3 wrong statements with accurate guidance that
  both forms work and explains the CLI flag's relationship to the
  env var.

.cursorrules, docs/GETTING_STARTED.md, docs/WEB_INTERFACE_GUIDE.md,
docs/PLUGIN_DEVELOPMENT_GUIDE.md
- Four places claimed "the plugin loader also falls back to plugins/".
  Verified that PluginManager.discover_plugins()
  (src/plugin_system/plugin_manager.py:154) only scans the
  configured directory — no fallback. The fallback to plugins/
  exists only in two narrower places: store_manager.py:1700-1718
  (store install/update/uninstall operations) and
  schema_manager.py:70-80 (schema lookup for the web UI form
  generator). Rewrote all four mentions with the precise scope.
  Added a recommendation to set plugin_system.plugins_directory
  to "plugins" for the smoothest dev workflow with
  dev_plugin_setup.sh symlinks.

docs/FONT_MANAGER.md
- The "Status" warning told plugin authors to use
  display_manager.font_manager.resolve_font(...) as a workaround for
  loading plugin fonts. Verified in src/font_manager.py that
  resolve_font() takes a family name, not a file path — so the
  workaround as written doesn't actually work. Rewrote to tell
  authors to load the font directly with PIL or freetype-py in their
  plugin.
- The same section said "the user-facing font override system in the
  Fonts tab still works for any element that's been registered via
  register_manager_font()". Verified in
  web_interface/blueprints/api_v3.py:5404-5428 that
  /api/v3/fonts/overrides is a placeholder implementation that
  returns empty arrays and contains "would integrate with the actual
  font system" comments — the Fonts tab does not have functional
  integration with register_manager_font() or the override system.
  Removed the false claim and added an explicit note that the tab
  is a placeholder.

docs/ADVANCED_FEATURES.md:523
- The on-demand section said REST/UI calls write a request "into the
  cache manager (display_on_demand_config key)". Wrong — verified
  via grep that api_v3.py:1622 and :1687 write to
  display_on_demand_request, and display_on_demand_config is only
  written by the controller during activation
  (display_controller.py:1195, cleared at :1221). Corrected the key
  name and added controller file:line references so future readers
  can verify.

docs/ADVANCED_FEATURES.md:803
- "Plugins using the background service" paragraph listed all
  scoreboard plugins but an orphaned "⏳ MLB (baseball)" bullet
  remained below from the old version of the section. Removed the
  orphan and added "baseball/MLB" to the inline list for clarity.

web_interface/README.md
- The POST /api/v3/system/action action list was incomplete. Verified
  in web_interface/app.py:1383,1386 that enable_autostart and
  disable_autostart are valid actions. Added both.
- The Plugin Store section was missing
  GET /api/v3/plugins/store/github-status (verified at
  api_v3.py:3296). Added it.
- The SSE line-range reference was app.py:607-615 but line 619
  contains the "Exempt SSE streams from CSRF and add rate limiting"
  block that's semantically part of the same feature. Extended the
  range to 607-619.

docs/GETTING_STARTED.md
- Rows/Columns step said "Columns: 64 or 96 (match your hardware)".
  The web UI's validation accepts any integer in 16-128. Clarified
  that 64 and 96 are the common bundled-hardware values but the
  valid range is wider.

Not addressed (out of scope for docs PR):

- .cursorrules:184 CodeRabbit comment flagged the non-existent
  cache_manager.delete() calls in src/common/api_helper.py:287 and
  src/plugin_system/resource_monitor.py:343. These are real CODE
  bugs, not doc bugs, and they're the first item in the planned
  post-docs-refresh code-cleanup PR (see
  /home/chuck/.claude/plans/warm-imagining-river.md). The docs in
  this PR correctly state that delete() doesn't exist on
  CacheManager — the fix belongs in the follow-up code PR that
  either adds a delete() shim or updates the two callers.

+The LEDMatrix project uses a plugin-based architecture. All display

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official email address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+This includes the LEDMatrix Discord server, GitHub repositories owned by
+ChuckBuilds, and any other forums hosted by or affiliated with the project.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement on the
+[LEDMatrix Discord](https://discord.gg/uW36dVAtcT) (DM a moderator or
+ChuckBuilds directly) or by opening a private GitHub Security Advisory if
+the issue involves account safety. All complaints will be reviewed and
+investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+

+# Contributing to LEDMatrix
+
+Thanks for considering a contribution! LEDMatrix is built with help from
+the community and we welcome bug reports, plugins, documentation
+improvements, and code changes.
+
+## Quick links
+
+- **Bugs / feature requests**: open an issue using one of the templates
+  in [`.github/ISSUE_TEMPLATE/`](.github/ISSUE_TEMPLATE/).
+- **Real-time discussion**: the
+  [LEDMatrix Discord](https://discord.gg/uW36dVAtcT).
+- **Plugin development**:
+  [`docs/PLUGIN_DEVELOPMENT_GUIDE.md`](docs/PLUGIN_DEVELOPMENT_GUIDE.md)
+  and the [`ledmatrix-plugins`](https://github.com/ChuckBuilds/ledmatrix-plugins)
+  repository.
+- **Security issues**: see [`SECURITY.md`](SECURITY.md). Please don't
+  open public issues for vulnerabilities.
+
+## Setting up a development environment
+
+1. Clone with submodules:
+   ```bash
+   git clone --recurse-submodules https://github.com/ChuckBuilds/LEDMatrix.git
+   cd LEDMatrix
+   ```
+2. For development without hardware, run the dev preview server:
+   ```bash
+   python3 scripts/dev_server.py
+   # then open http://localhost:5001
+   ```
+   See [`docs/DEV_PREVIEW.md`](docs/DEV_PREVIEW.md) for details.
+3. To run the full display in emulator mode:
+   ```bash
+   EMULATOR=true python3 run.py
+   ```
+4. To target real hardware on a Raspberry Pi, follow the install
+   instructions in the root [`README.md`](README.md).
+
+## Running the tests
+
+```bash
+pip install -r requirements.txt
+pytest
+```
+
+See [`docs/HOW_TO_RUN_TESTS.md`](docs/HOW_TO_RUN_TESTS.md) for details
+on test markers, the per-plugin tests, and the web-interface
+integration tests.
+
+## Submitting changes
+
+1. **Open an issue first** for non-trivial changes. This avoids
+   wasted work on PRs that don't fit the project direction.
+2. **Create a topic branch** off `main`:
+   `feat/<short-description>`, `fix/<short-description>`,
+   `docs/<short-description>`.
+3. **Keep PRs focused.** One conceptual change per PR. If you find
+   adjacent bugs while working, fix them in a separate PR.
+4. **Follow the existing code style.** Python code uses standard
+   `black`/`ruff` conventions; HTML/JS in `web_interface/` follows the
+   patterns already in `templates/v3/` and `static/v3/`.
+5. **Update documentation** alongside code changes. If you add a
+   config key, document it in the relevant `*.md` file (or, for
+   plugins, in `config_schema.json` so the form is auto-generated).
+6. **Run the tests** locally before opening the PR.
+7. **Use the PR template** — `.github/PULL_REQUEST_TEMPLATE.md` will
+   prompt you for what we need.
+
+## Commit message convention
+
+Conventional Commits is encouraged but not strictly enforced:
+
+- `feat: add NHL playoff bracket display`
+- `fix(plugin-loader): handle missing class_name in manifest`
+- `docs: correct web UI port in TROUBLESHOOTING.md`
+- `refactor(cache): consolidate strategy lookup`
+
+Keep the subject under 72 characters; put the why in the body.
+
+## Contributing a plugin
+
+LEDMatrix plugins live in their own repository:
+[`ledmatrix-plugins`](https://github.com/ChuckBuilds/ledmatrix-plugins).
+Plugin contributions go through that repo's
+[`SUBMISSION.md`](https://github.com/ChuckBuilds/ledmatrix-plugins/blob/main/SUBMISSION.md)
+process. The
+[`hello-world` plugin](https://github.com/ChuckBuilds/ledmatrix-plugins/tree/main/plugins/hello-world)
+is the canonical starter template.
+
+## Reviewing pull requests
+
+Maintainer review is by [@ChuckBuilds](https://github.com/ChuckBuilds).
+Community review is welcome on any open PR — leave constructive
+comments, test on your hardware if applicable, and call out anything
+unclear.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+# Security Policy
+
+## Reporting a vulnerability
+
+If you've found a security issue in LEDMatrix, **please don't open a
+public GitHub issue**. Disclose it privately so we can fix it before it's
+exploited.
+
+### How to report
+
+Use one of these channels, in order of preference:
+
+1. **GitHub Security Advisories** (preferred). On the LEDMatrix repo,
+   go to **Security → Advisories → Report a vulnerability**. This
+   creates a private discussion thread visible only to you and the
+   maintainer.
+   - Direct link: <https://github.com/ChuckBuilds/LEDMatrix/security/advisories/new>
+2. **Discord DM**. Send a direct message to a moderator on the
+   [LEDMatrix Discord](https://discord.gg/uW36dVAtcT). Don't post in
+   public channels.
+
+Please include:
+
+- A description of the issue
+- The version / commit hash you're testing against
+- Steps to reproduce, ideally a minimal proof of concept
+- The impact you can demonstrate
+- Any suggested mitigation
+
+### What to expect
+
+- An acknowledgement within a few days (this is a hobby project, not
+  a 24/7 ops team).
+- A discussion of the issue's severity and a plan for the fix.
+- Credit in the release notes when the fix ships, unless you'd
+  prefer to remain anonymous.
+- For high-severity issues affecting active deployments, we'll
+  coordinate disclosure timing with you.
+
+## Scope
+
+In scope for this policy:
+
+- The LEDMatrix display controller, web interface, and plugin loader
+  in this repository
+- The official plugins in
+  [`ledmatrix-plugins`](https://github.com/ChuckBuilds/ledmatrix-plugins)
+- Installation scripts and systemd unit files
+
+Out of scope (please report upstream):
+
+- Vulnerabilities in `rpi-rgb-led-matrix` itself —
+  report to <https://github.com/hzeller/rpi-rgb-led-matrix>
+- Vulnerabilities in Python packages we depend on — report to the
+  upstream package maintainer
+- Issues in third-party plugins not in `ledmatrix-plugins` — report
+  to that plugin's repository
+
+## Known security model
+
+LEDMatrix is designed for trusted local networks. Several limitations
+are intentional rather than vulnerabilities:
+
+- **No web UI authentication.** The web interface assumes the network
+  it's running on is trusted. Don't expose port 5000 to the internet.
+- **Plugins run unsandboxed.** Installed plugins execute in the same
+  Python process as the display loop with full file-system and
+  network access. Review plugin code (especially third-party plugins
+  from arbitrary GitHub URLs) before installing. The Plugin Store
+  marks community plugins as **Custom** to highlight this.
+- **The display service runs as root** for hardware GPIO access. This
+  is required by `rpi-rgb-led-matrix`.
+- **`config_secrets.json` is plaintext.** API keys and tokens are
+  stored unencrypted on the Pi. Lock down filesystem permissions on
+  the config directory if this matters for your deployment.
+
+These are documented as known limitations rather than bugs. If you
+have ideas for improving them while keeping the project usable on a
+Pi, open a discussion — we're interested.
+
+## Supported versions
+
+LEDMatrix is rolling-release on `main`. Security fixes land on `main`
+and become available the next time users run **Update Code** from the
+web UI's Overview tab (which does a `git pull`). There are no LTS
+branches.

 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.

 # LEDMatrix Plugin Architecture Specification

 This document outlines the transformation of the LEDMatrix project into a modular, plugin-based architecture that enables user-created displays.

 ## Overview
 
 Plugins can specify custom icons that appear next to their name in the web interface tabs. This makes your plugin instantly recognizable and adds visual polish to the UI.

+LEDMatrix is a modular, plugin-based system where users create, share,

 ## Key Decisions
 
-✅ **Gradual Migration**: Existing managers stay, plugins added alongside  
+✅ **Plugin-First**: All display features (calendar excepted) are now plugins
-✅ **Migration Required**: Breaking changes in v3.0, tools provided  
+✅ **GitHub Store**: Discovery from `ledmatrix-plugins` registry plus
-✅ **GitHub Store**: Simple discovery, packages from repos  
+   any GitHub URL
-✅ **Plugin Location**: `./plugins/` directory  
+✅ **Plugin Location**: configured by `plugin_system.plugins_directory`

-## 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)?

 ### Quiet Mode
 Reduce logging output:

+# Permission Fix Scripts
+
+This directory contains shell scripts for repairing file/directory
+permissions on a LEDMatrix installation. They're typically only needed
+when something has gone wrong — for example, after running parts of the
+install as the wrong user, after a manual file copy that didn't preserve
+ownership, or after a permissions-related error from the display or
+web service.
+
+Most of these scripts require `sudo` since they touch directories
+owned by the `ledmatrix` service user or by `root`.
+
+## Scripts
+
+- **`fix_assets_permissions.sh`** — Fixes ownership and write
+  permissions on the `assets/` tree so plugins can download and cache
+  team logos, fonts, and other static content.
+
+- **`fix_cache_permissions.sh`** — Fixes permissions on every cache
+  directory the project may use (`/var/cache/ledmatrix/`,
+  `~/.cache/ledmatrix/`, `/opt/ledmatrix/cache/`, project-local
+  `cache/`). Also creates placeholder logo subdirectories used by the
+  sports plugins.
+
+- **`fix_plugin_permissions.sh`** — Fixes ownership on the plugins
+  directory so both the root display service and the web service user
+  can read and write plugin files (manifests, configs, requirements
+  installs).
+
+- **`fix_web_permissions.sh`** — Fixes permissions on log files,
+  systemd journal access, and the sudoers entries the web interface
+  needs to control the display service.
+
+- **`fix_nhl_cache.sh`** — Targeted fix for NHL plugin cache issues
+  (clears the NHL cache and restarts the display service).
+
+- **`safe_plugin_rm.sh`** — Validates that a plugin removal path is
+  inside an allowed base directory before deleting it. Used by the web
+  interface (via sudo) when a user clicks **Uninstall** on a plugin —
+  prevents path-traversal abuse from the web UI.
+
+## When to use these
+
+Most users never need to run these directly. The first-time installer
+(`first_time_install.sh`) sets up permissions correctly, and the web
+interface manages plugin install/uninstall through the sudoers entries
+the installer creates.
+
+Run these scripts only when:
+
+- You see "Permission denied" errors in `journalctl -u ledmatrix` or
+  the web UI Logs tab.
+- You manually copied files into the project directory as the wrong
+  user.
+- You restored from a backup that didn't preserve ownership.
+- You moved the LEDMatrix directory and need to re-anchor permissions.
+
+## Usage
+
+```bash
+# Run from the project root
+sudo ./scripts/fix_perms/fix_cache_permissions.sh
+sudo ./scripts/fix_perms/fix_assets_permissions.sh
+sudo ./scripts/fix_perms/fix_plugin_permissions.sh
+sudo ./scripts/fix_perms/fix_web_permissions.sh
+```
+
+If you're not sure which one you need, run `fix_cache_permissions.sh`
+first — it's the most commonly needed and creates several directories
+the other scripts assume exist.
