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.
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.
