* Adding tracks to a playlist no longer fails past ~341 songs — writes are sent to the server in batches instead of one oversized request, so playlists of any size build correctly.
* Adding and merging into large playlists is faster: playlist membership is cached in memory for de-duplication instead of re-fetching the whole playlist on every add.
+### Queue — rows no longer stuck showing "…"

+* Queue rows that were far from the currently playing track (e.g. after starting a large playlist from the middle, or scrolling the queue) no longer stay stuck on a "…" placeholder — the queue now loads track details for whatever you scroll to, in the desktop queue panel, the mobile queue drawer, and the fullscreen "up next" overlay.
