fix(web): treat only 2xx as a successful display save

Review feedback on #422.

- showDisplaySaveResult tested `xhr.status >= 400` for failure, so a
  network error — which reports status 0 — was waved through as
  "Display settings saved". That's the same class of false-success bug
  this branch set out to fix. Test the 2xx range instead, and let a
  response body refine a successful verdict without overturning a
  failed one.
- Annotate the _copies_fits_hardware helper, matching the annotated
  helpers already in api_v3.py.
- Cover the vertical divisibility branch: chain_length 2 would divide
  evenly, so only parallel 3 can produce the rejection, which pins the
  branch to the right hardware dimension.

+# Creating Skins
+
+A skin restyles a sports scoreboard (live / recent / upcoming) without
+forking the plugin: the plugin keeps fetching data, scheduling, caching, and
+doing vegas mode; your skin only draws. Architecture background:
+[SKIN_SYSTEM.md](SKIN_SYSTEM.md).
+
+## Quick start
+
+```bash
+cp -r skins/example-classic-baseball skins/my-skin
+# edit skins/my-skin/skin.json  -> set id ("my-skin"), name, author, class_name
+# edit skins/my-skin/skin.py    -> rename the class, start restyling
+python scripts/validate_skin.py --skin my-skin
+```
+
+The validator renders your skin against bundled fixture games at several
+panel sizes with **no hardware, no network, no running service**, saves PNGs
+(plus 4x previews) to `skin_renders/`, and fails loudly on errors. Iterate:
+edit → validate → look at the PNGs.
+
+To see it on your matrix, add to your plugin's section in `config/config.json`:
+
+```json
+"baseball-scoreboard": {
+  "skin": "my-skin",
+  "skin_options": { }
+}
+```
+
+or pick it from the **Visual Skin** dropdown in the web UI (it appears once a
+matching skin is installed). `"skin"` also accepts a per-mode mapping:
+`{"live": "my-skin", "recent": "built-in"}`.
+
+## The manifest (`skin.json`)
+
+```json
+{
+  "id": "my-skin",
+  "name": "My Skin",
+  "version": "1.0.0",
+  "author": "you",
+  "description": "What it looks like",
+  "skin_api_version": "1.0.0",
+  "targets": {
+    "sports": ["baseball"],
+    "sport_keys": ["mlb", "milb"],
+    "plugins": []
+  },
+  "entry_point": "skin.py",
+  "class_name": "MySkin",
+  "modes": ["live", "recent", "upcoming"],
+  "preview": "preview.png"
+}
+```
+
+Field notes: `id` must equal the directory name; `skin_api_version`'s major
+version must match the host's `SKIN_API_VERSION` or the skin is refused at
+load; `targets` takes sport families (`sports`), exact sport keys
+(`sport_keys`), and/or exact plugin ids (`plugins`) — any match applies.
+
+## The renderer (`skin.py`)
+
+```python
+from src.skin_system.skin_base import ScoreboardSkin, SkinContext
+
+class MySkin(ScoreboardSkin):
+    def render_live(self, ctx: SkinContext, game: dict) -> bool:
+        score = f"{game.get('away_score', '0')}-{game.get('home_score', '0')}"
+        fit = ctx.layout.fit_text(score, ctx.layout.bounds)
+        ctx.draw_fit(fit, ctx.layout.bounds)
+        return True   # True = "I drew it"; False = use the built-in layout
+```
+
+Implement only the modes you care about — anything else falls back to the
+plugin's built-in rendering. Return `False` to decline a specific game (e.g.
+a layout that only makes sense while a game is live).
+
+### The rules (they keep your skin from breaking the display)
+
+1. **Draw only onto `ctx.canvas`** (via the helpers or `ctx.draw`). Never
+   reassign `ctx.canvas`, never touch the display or call any update method.
+2. **No I/O in render paths.** No network, no file loads per frame —
+   `render_live` runs every display pass, and a slow render stalls the whole
+   matrix (the host warns at >150 ms). Use `ctx.load_logo` (cached) and
+   `cache_key=` for images.
+3. **Derive everything from `(ctx, game)`.** Skins must be stateless: the
+   live/recent/upcoming modes each get their own instance.
+4. **Always `.get()` optional keys.** Only the guaranteed keys below are
+   promised to exist.
+5. **Never hardcode pixel positions for the panel.** Use `ctx.width`/
+   `ctx.height`, `ctx.layout` regions and `fit_text` — your skin will be run
+   at sizes you didn't test (64x32, 128x64, vegas cards).
+6. **No third-party dependencies.** Stdlib + PIL + what `ctx` provides.
+
+A skin that raises 3 renders in a row is disabled until the service restarts
+(the built-in layout takes over), so a bug is cosmetic — but check your logs.
+
+## SkinContext reference
+
+| Member | What it is |
+|---|---|
+| `ctx.canvas` / `ctx.draw` | Fresh RGB `PIL.Image` at display size + its `ImageDraw` (raw-PIL escape hatch) |
+| `ctx.width`, `ctx.height` | Canvas size — the only size truth |
+| `ctx.layout` | `LayoutContext` (see [ADAPTIVE_LAYOUT.md](ADAPTIVE_LAYOUT.md)): `bounds`, `fit_text`, `fit_text_proportional`, `fit_image`, `px`, `by_tier` |
+| `ctx.draw_fit(fit, box, color, align, valign)` | Draw a `fit_text` result aligned in a `Region` (handles BDF fonts) |
+| `ctx.draw_text(text, x, y, color, font)` | Positioned text (handles BDF fonts) |
+| `ctx.draw_image(img, box, mode, align, valign, cache_key)` | Fit + paste an image with alpha; no-ops on `None` |
+| `ctx.load_logo("home" \| "away")` | Team logo as RGBA, or `None` (always handle `None`). Cached after first use; see note below |
+| `ctx.draw_text_outlined(text, (x, y), font, fill, outline_color)` | The classic scorebug outlined text (TTF fonts only) |
+| `ctx.fonts` | The host's font dict — keys `score`, `time`, `team`, `status`, `detail`, `rank` |
+| `ctx.options` | Your user's `skin_options` from config |
+| `ctx.sport`, `ctx.view_model_version`, `ctx.logger` | Context metadata + logger |
+
+**A note on `ctx.load_logo` vs the no-I/O rule:** `load_logo` is the one
+sanctioned exception. It goes through the host's logo cache — after the
+first call per team it's a pure in-memory lookup. If a logo file is missing
+on disk, the *first* call may download it, exactly like the built-in
+renderer does for the same game (a skin is never worse than built-in here).
+Always pass a stable `cache_key` when drawing it, never load image files
+yourself in a render path, and always handle `None`.
+
+The default layout idiom — carve regions, then fit text into them:
+
+```python
+from src.adaptive_layout import scoreboard_regions
+
+regions = scoreboard_regions(ctx.layout.bounds, ctx=ctx.layout)
+ctx.draw_image(ctx.load_logo("away"), regions.away_slot, cache_key=f"logo:{game.get('away_abbr')}")
+ctx.draw_image(ctx.load_logo("home"), regions.home_slot, cache_key=f"logo:{game.get('home_abbr')}")
+fit = ctx.layout.fit_text("3-5", regions.score_area)
+ctx.draw_fit(fit, regions.score_area)
+```
+
+`Region` supports `split_h`/`split_v`/`inset`/`top_band`/`bottom_band`/
+`left_col`/`right_col` for custom carves. Raw `ctx.draw.rectangle/polygon/
+ellipse/...` is always available for custom marks (see the bases diamond in
+the example skin).
+
+## The game view model
+
+Guaranteed for every sport (view model v1.0 — renaming these breaks skins and
+is treated as a breaking change upstream):
+
+| Key | Notes |
+|---|---|
+| `id` | Event id (string) |
+| `status_text` | Display-ready status, e.g. `"Final"`, `"7:30 PM"`, `"Bot 7th"` |
+| `is_live`, `is_final`, `is_upcoming`, `is_halftime` | Booleans |
+| `game_date`, `game_time` | Pre-formatted local date/time strings |
+| `start_time_utc` | UTC `datetime` |
+| `home_abbr`, `away_abbr` | Team abbreviations (can be 2–5 chars — fit, don't assume) |
+| `home_id`, `away_id` | Team ids |
+| `home_score`, `away_score` | **Strings**, not ints |
+| `home_record`, `away_record` | `"58-33"` or `""` (0-0 records are blanked) |
+| `home_logo_path`, `away_logo_path` | Prefer `ctx.load_logo` over touching these |
+
+Sport extras (present for that sport, still `.get()` defensively):
+
+- **baseball**: `inning` (int), `inning_half` (`"top"`/`"bottom"`), `balls`,
+  `strikes`, `outs` (ints), `bases_occupied` (`[first, second, third]`
+  booleans), `series_summary` (str)
+- **football**: `period`, `period_text`, `clock`, `home_timeouts`,
+  `away_timeouts`, `down_distance_text`, `down_distance_text_long`,
+  `is_redzone`, `possession`, `possession_indicator` (`"home"`/`"away"`),
+  `scoring_event`
+- **basketball**: `period`, `period_text`, `clock`
+- **hockey**: `period`, `period_text`, `clock`, `power_play`, `penalties`,
+  `home_shots`, `away_shots`
+
+Optional everywhere (only when the user enabled the feature): `odds` (dict),
+`series_summary`, rankings-related fields.
+
+Fixture copies of these dicts live in `src/skin_system/fixtures/` — that's
+exactly what the validator feeds your skin.
+
+## Vegas mode
+
+You get vegas support for free: vegas captures the normal display output,
+which is already your skin's rendering. Optionally implement
+`render_vegas_card(ctx, game)` to return a purpose-built card at
+`ctx.width x ctx.height` (sizes vary — never assume 128x32).
+
+## Building a skin with Claude Code
+
+Skins are ideal Claude Code projects: small, isolated, and verifiable with
+one command. Paste this to start:
+
+> You are building a **display skin** for LEDMatrix — a visual overlay for a
+> sports scoreboard on a small LED matrix (commonly 128x32 or 64x32 pixels).
+> First read `docs/CREATING_SKINS.md` and the reference skin in
+> `skins/example-classic-baseball/`.
+>
+> Rules:
+> - Create/modify files ONLY under `skins/<my-skin-id>/`. Do NOT modify
+>   anything in `src/`, `scripts/`, the plugins, or any other skin.
+> - Render only from the `game` dict and `ctx` helpers. No network calls, no
+>   per-frame file I/O, no new pip dependencies, no touching the display —
+>   draw onto `ctx.canvas` and return True.
+> - Use `ctx.layout` regions and `fit_text` for positioning so the skin works
+>   at any panel size; use `.get()` for every optional game key.
+> - After every change run
+>   `python scripts/validate_skin.py --skin <my-skin-id>` and LOOK at the
+>   PNGs it writes to `skin_renders/` (the `_x4.png` files are easiest to
+>   read). Iterate until it passes and looks right at both 128x32 and 64x32.
+>
+> What I want it to look like: <describe your layout — where logos, score,
+> status go; colors; what shows during live vs upcoming vs final>
+
+Tips that keep Claude (and you) out of trouble:
+
+- One mode at a time: get `render_live` right before touching the others —
+  unimplemented modes automatically use the built-in look.
+- Ask for edge-case renders: long team abbreviations, missing logos
+  (`ctx.load_logo` returning `None`), 0-0 records, extra innings/OT.
+- If the render looks cramped at 64x32, ask Claude to use
+  `ctx.layout.by_tier(...)` to drop elements on small panels rather than
+  shrinking everything.
+- Never let it "fix" a problem by editing `src/` — if the skin can't do
+  something within its directory, that's a feature request, not a workaround.
+
+## Pre-publish checklist
+
+- [ ] `python scripts/validate_skin.py --skin <id> --size 128x32 --size 64x32 --size 128x64` passes
+- [ ] Looked at every PNG in `skin_renders/` — nothing clipped or overlapping
+- [ ] Handles a missing logo (`None`) without crashing — temporarily point a
+      fixture's logo path at a nonexistent file to test
+- [ ] Long abbreviations (`"TA&M"`, 4–5 chars) don't overflow
+- [ ] No render warning above the time budget
+- [ ] `skin.json`: `id` matches the directory, `version` set,
+      `skin_api_version` matches the host, targets correct
+- [ ] `preview.png` added (grab your favorite `_x4` render)
+- [ ] Tested on real hardware if you have it — a Pi is much slower than your
+      dev machine
+
+Distribute by publishing the directory as a git repo (users
+`git clone <repo> skins/<id>`), or submit it to the plugin registry as an
+entry with `"type": "skin"` (see [SKIN_SYSTEM.md](SKIN_SYSTEM.md) §Distribution).
+
+**Trust note:** a skin is Python running inside the display service — the
+same trust level as a plugin. Review code before installing skins from
+others.

+# Skin System Architecture
+
+Skins are user-installable **visual overlays** for the sports scoreboards.
+A skin replaces only the *look* of a scoreboard — the host plugin keeps doing
+data fetching, scheduling, caching, dedup, live-priority takeover, and vegas
+mode. If you only want to **build** a skin, read
+[CREATING_SKINS.md](CREATING_SKINS.md); this document explains how the system
+works and why it is shaped this way.
+
+## Why skins instead of forks
+
+Before skins, changing a scoreboard's layout meant forking the whole plugin
+(e.g. the community MLB scoreboard fork). The fork gets the new look but loses
+everything the maintained plugin keeps earning: duration/scheduling behavior,
+vegas mode support, caching and background-fetch improvements, bug fixes. It
+also silently drifts: every upstream improvement now has to be re-ported by
+hand.
+
+A skin inverts that trade. The plugin remains stock and keeps updating through
+the store; the skin is ~100 lines of pure rendering code that receives the
+plugin's already-fetched data each frame. Uninstalling the skin (or the skin
+crashing) simply restores the built-in look.
+
+```text
+              (unchanged)                        (the skin seam)
+ ESPN API ──► update() ──► game view model ──► _render_game() ──► display
+              fetching        (a dict)          │         │
+              caching                           │         └─ built-in
+              scheduling                        └─ skin.render_<mode>(ctx, game)
+              live priority                        draws onto ctx.canvas
+```
+
+## The render funnel
+
+Every sports scoreboard (baseball, football, basketball, hockey — anything
+built on `src/base_classes/sports.py`) renders through exactly one seam:
+`SportsCore._render_game(game, force_clear)`.
+
+1. The mode class's `display()` (live, `SportsUpcoming`, `SportsRecent`)
+   picks `self.current_game` and calls `_render_game`.
+2. `_render_game` lazily loads the configured skin (once, on first render —
+   a broken skin can never block plugin startup).
+3. If a skin is active, the host builds a `SkinContext` — a fresh black
+   canvas at the current display size plus layout/font/logo helpers — and
+   calls the skin's `render_live` / `render_recent` / `render_upcoming`
+   with a **copy** of the game dict.
+4. If the skin returns `True`, the canvas is composited onto the display.
+   If it returns `False`, isn't implemented for that mode, or raises, the
+   built-in `_draw_scorebug_layout` runs instead.
+
+Key properties that fall out of this design:
+
+- **Per-mode fallback.** A skin that only implements `render_live` gets the
+  stock recent/upcoming screens for free.
+- **Three strikes.** A skin that raises 3 times in a row is disabled for the
+  rest of the session (one loud error log per failure); the display never
+  goes dark. Restarting the service re-arms it.
+- **Copies, not references.** Skins receive a shallow copy of the game dict,
+  so a buggy skin cannot corrupt the plugin's scheduling state.
+- **Vegas mode works untouched.** Vegas capture falls back to grabbing the
+  regular `display()` output, which is already skin-rendered. Skins can
+  additionally implement `render_vegas_card` for purpose-built scroll cards,
+  and hosts can call `SportsCore.render_skin_card(game, size)` to use it.
+- **Hot-loop caution.** `render_live` runs every display-loop pass during a
+  live game. The host logs a warning when a skin render exceeds 150 ms, and
+  `scripts/validate_skin.py` enforces a budget at development time — but
+  Python cannot forcibly time-out a stuck render, so a skin that blocks
+  (network I/O, giant image ops) stalls the display. This is why the rules
+  in CREATING_SKINS.md ban I/O in render paths.
+
+## The view model contract
+
+The `game` dict a skin receives is the plugin's already-extracted view model
+(`SportsCore._extract_game_details_common` plus per-sport extras from
+`src/base_classes/{baseball,basketball,football,hockey}.py`).
+
+- **Guaranteed keys (view model v1.0)** — always present for every sport:
+  `id`, `game_time`, `game_date`, `start_time_utc` (a UTC `datetime`),
+  `status_text`, `is_live`, `is_final`, `is_upcoming`, `is_halftime`,
+  `home_abbr`/`away_abbr`, `home_id`/`away_id`, `home_score`/`away_score`
+  (**strings**), `home_logo_path`/`away_logo_path`, `home_record`/`away_record`.
+- **Sport extras** — documented per sport in CREATING_SKINS.md (e.g. baseball
+  adds `inning`, `inning_half`, `balls`, `strikes`, `outs`, `bases_occupied`).
+- **Optional keys** (`odds`, rankings, `series_summary`, …) are present only
+  when the feature is enabled — skins must always use `.get()`.
+
+Versioning policy: additive changes bump the minor version
+(`VIEW_MODEL_VERSION` in `src/skin_system/skin_base.py`, surfaced to skins as
+`ctx.view_model_version`); renaming or removing a guaranteed key requires a
+major bump plus a compat shim. `test/test_skin_system.py::TestViewModelContract`
+fails CI if a guaranteed key disappears from the extractor.
+
+Separately, `SKIN_API_VERSION` versions the Python API (`ScoreboardSkin`,
+`SkinContext`). The loader refuses a skin whose manifest declares a different
+major version and falls back to the built-in renderer with a clear
+"skin needs an update" log line.
+
+## Package layout and lifecycle
+
+```text
+skins/<skin-id>/
+  skin.json      # manifest (required)
+  skin.py        # ScoreboardSkin subclass (required)
+  preview.png    # optional, shown by the web UI
+  assets/        # optional skin-local images
+  helpers.py ... # optional extra modules (namespaced per skin at import)
+```
+
+Skins live in the central `skins/` directory — deliberately **not** inside the
+plugin's directory, because plugin reinstall/update deletes the whole plugin
+directory and a skin must survive that. One skin can also target several
+plugins (mlb + milb).
+
+Lifecycle: discovered lazily on first render → manifest validated → API major
+version gated → module imported under a namespaced `sys.modules` key (two
+skins can both ship a `helpers.py`, same scheme plugins use) → instantiated
+with `(manifest, options)`. Every failure logs and falls back to built-in.
+
+Skins should be **stateless**: the live, recent, and upcoming mode classes
+each hold their own skin instance, so derive everything from `(ctx, game)`.
+
+## Selection and configuration
+
+Inside the plugin's own config section in `config/config.json`:
+
+```json
+"baseball-scoreboard": {
+  "skin": "retro-baseball",
+  "skin_options": { "accent_color": [255, 80, 0] }
+}
+```
+
+`"skin"` is either one id for all modes or a per-mode mapping
+(`{"live": "retro-baseball", "recent": "built-in"}`). Absent, empty, or
+`"built-in"` means the stock renderer. Because this rides the plugin's config
+section, it persists across plugin reinstalls like every other setting.
+
+The web UI shows a **Visual Skin** dropdown for plugins that have matching
+skins installed: `SchemaManager.inject_skin_selector` adds an enum to the
+*served* schema only. Validation never sees the enum — so a config that
+references an uninstalled skin stays valid (rendering just falls back), and
+the currently-configured value is always kept selectable. `GET /api/v3/skins`
+lists installed skins (optionally filtered by `?plugin_id=`).
+
+## Distribution
+
+- **Manual:** `git clone <skin repo> skins/<skin-id>` — that's the whole
+  install. No manifest bumps, no `update_registry.py`; skins are not monorepo
+  plugins.
+- **Store:** registry entries with `"type": "skin"` install through the same
+  `plugins.json` pipeline; `PluginStoreManager` routes them to `skins/`,
+  validates `skin.json` (including the API major version) instead of
+  `manifest.json`, and never installs dependencies — skins are render-only
+  (stdlib + PIL + the provided context, no third-party packages in v1).
+
+## Trust model
+
+A skin is Python executing inside the display service — **exactly the same
+trust level as a plugin**, even though "skin" sounds cosmetic. Only install
+skins from sources you'd be willing to install a plugin from.
+
+## v2 directions (not in v1)
+
+- A generic `BasePlugin` opt-in (`render_with_skin()`) so non-sports plugins
+  (weather, music) can offer skinnable layouts; `skin_runtime` is already
+  sports-agnostic in anticipation.
+- Store UI: preview gallery, one-click install from the skin browser.
+- An update path for git-cloned skins (today: re-clone or store reinstall).
+- Animation support in skins (today the API is one frame per render call;
+  stateful tricks work but are at-your-own-risk).

+Add `"x-advanced": true` to any top-level, non-object property to move it out
+of the main form and into a single collapsed **Advanced Settings** section at
+the bottom of the plugin's configuration page:
+
+```json
+{
+  "properties": {
+    "city": {
+      "type": "string",
+      "title": "City"
+    },
+    "request_timeout": {
+      "type": "integer",
+      "default": 10,
+      "description": "HTTP timeout in seconds",
+      "x-advanced": true
+    }
+  }
+}
+```
+
+Guidelines:
+
+- Use it for fine-tuning knobs most users never touch (timeouts, retry
+  behavior, cache TTLs, styling overrides). Anything a first-time user must
+  set to get the plugin working should stay basic.
+- Nothing is hidden permanently — the section expands on click, and the
+  settings search finds and auto-expands advanced fields like any others.
+- The flag is ignored on `object`-type properties (they already render as
+  their own collapsible sections) and is safely ignored by older cores, so
+  adding it never breaks compatibility.

+1. Breakpoint utility audit: app.css hand-maintains a Tailwind-style utility

+   that no CSS rule defines — it silently no-ops. This once left the header
+   search box and system stats invisible at every screen width. The audit
+   diffs classes used in templates against classes defined in app.css.
+
+2. Asset reference audit: every url_for('static', filename=...) in the
+   templates must point to a file that exists, so a renamed/moved asset
+   can't ship as a broken <script>/<link>/<img>.
+
+3. debugLog globals audit: any static JS file calling debugLog() (a global
+   defined in base.html) must declare it in a /* global */ header so linting
+   stays clean and the dependency is explicit.

+ * Plugin Order List — shared drag-and-drop reorder list of enabled plugins.
+ *
+ * Factored out of the Vegas Scroll section of display.html so both Vegas mode

+ * one draggable row per enabled plugin into a container and keeps a hidden
+ * input's value in sync as a JSON array of plugin ids in display order.
+ *
+ * Usage:
+ *   PluginOrderList.init({
+ *       containerId: 'vegas_plugin_order',        // rows render here
+ *       orderInputId: 'vegas_plugin_order_value', // hidden input, JSON array of ids

+ *           // include-checkbox per row; unchecked ids collect here (JSON array)
+ *       showVegasModeBadge: true                  // optional: Scroll/Fixed/Static badge
+ *   });
+ *
+ * The container re-renders from /api/v3/plugins/installed each init; the
