PlayerBar reads playbackState + mediaItem streams; hidden when no
queue. Home track-row tap, album play button, album track tap, artist
play button (shuffle) all route to playerActions.playTracks. Token +
baseUrl forwarded to the audio handler before each new queue.
LikedIdsController loads /api/likes/ids once and mutates the local set
on toggle. Failed mutations roll the set back so the icon never lies.
Wired into ArtistDetail header, AlbumDetail header, and per-track in
the album track list.
Headers carry placeholder play buttons (wired in Task 18) + room for
LikeButton (Task 16). Artist screen has a 2-column album grid; album
screen has a track list with mm:ss durations. Routes :id-parameterized
under the shell so the PlayerBar persists.
Sections mirror the web home: Recently added · Rediscover (albums +
artists) · Most played · Last played artists. Tap routes pushed for
albums/artists; track-tap is wired in the player task. Pull-to-refresh
re-fetches /api/home.
HorizontalScrollRow takes an optional shared ScrollController so
multi-row sections (Most played: 3 rows) couple their scroll like the
web HorizontalScrollRow.svelte. Cards fall back to the synced
album-fallback.svg when coverUrl is empty.
LibraryApi wraps GET /api/home, /api/artists/{id}(/tracks),
/api/albums/{id}. dioProvider builds an authenticated dio (token
resolver reads session_token from secure storage on every request).
homeProvider, artistProvider(id), albumProvider(id) sit on top.
