The now-playing affordance — the accent pill on the row's left edge and the
eq bars in the number cell — never appeared for an offline row on the very
view it was played from. `TrackRow` asked one question,
QbzPlayer.npTrackId === item.id
and for a `qobuz_download` row the two sides come from different id spaces:
the queue id is the QOBUZ CATALOG id (the offline tier is keyed on it) while
every Local Library list draws the row with its `library.db` id. They never
matched, so the row sat dark while its own audio played.
The reference has a second published id for exactly this and the port never
carried it over: `NowPlayingState.local-track-id` (playback.rs:1978-1986).
This adds its twin, `QbzPlayer.npLocalTrackId`, and makes the row match
either.
Published for Offline rows ONLY, and that restriction is the safety of it:
`source_item_id_hint` is a shared slot carrying a Plex ALBUM key and a media
server's own item id for those sources, so publishing it unconditionally
would hand a list a number from another id space and light the wrong row.
It stays empty elsewhere, which makes the second test inert there.
Scope checked by driving the window rather than reasoned about: the pill and
the play glyph land on the right row for local user files, Plex, Jellyfin and
Subsonic both before and after this change — offline was the only source
whose id diverged. The other three surfaces that ask the same question need
no alias: the queue panel and the kiosk album carry queue ids, and the
purchases list carries catalog ids.
