Album-card click plays the album: get_album -> QueueTrack vec ->
set_queue -> play_track_resolved (tier walk stays in the core). 1 Hz
poll publishes position/meta/quality into the NowPlaying model; end-of-
track edge auto-advances with meta refresh (traced live: 24-bit/48kHz
CMAF stream, position advancing, track 2/3 transitions). Transport
invokables rewired to real core calls; queue panel shows NOW PLAYING +
numbered UP NEXT from get_queue_state. Public QbzCore API proved
sufficient — protected audio/player crates untouched. Named gaps:
no mute API, no playback event stream, auto-advance/prefetch semantics
remain frontend glue (~150 lines every UI must port).
