 A focused, editorial single-track view in `DeepDrftPublic.Client`. The track gallery answers "what is in the library"; this page answers "tell me about *this* track" — full metadata, cover art, and a single prominent play affordance, styled to feel like a record-sleeve back-cover rather than a form. Link-only for now (reached from a gallery card / Now Playing), not a top-level nav entry.

 - Render mode `InteractiveWebAssembly` (server prerender → WASM hydrate) mirrors `TracksView` consistency.
 - `TrackDetailViewModel` is scoped (per-instance), not singleton — navigating between `/track/A` and `/track/B` reuses the same scoped instance, so `Load` must fully reset state to prevent cross-navigation bleed.
 - Play button implements the same `PlayerService.StateChanged` subscription pattern as `TracksView` — mandatory for label coherence when the dock bar drives state.
-- Cover-art default (placeholder) is intentional and designed to be the resting state, not degraded; the page ships immediately without waiting for 2.1 image-vault wiring. Once 2.1 lands and `api/image/{entryKey}` exists on `DeepDrftContent`, the `<img src>` binding swaps in without further component changes (the placeholder's `onerror` fallback ensures graceful degradation if a vault entry is missing).
+- Cover-art integration (2026-06-08): the page now displays album art via a `MudPaper` div with `background-image: url('api/image/{entryKey}')` when `ImagePath` is present; a placeholder with the `Album` glyph renders when unavailable. CSS background rendering degrades gracefully (blank surface) if a vault entry is missing.
 - Page is link-only navigation (not in the header `MenuPages`); reachability depends on inbound links from `TrackCard` and Now Playing surfaces, which were wired simultaneously.
