buildListenBrainzPlaylistsHtml (shared by both sections) now emits a grid of mix cards instead of
full-width track-table subsections — each playlist is a card that opens its tracks (lazy-loaded from
/api/discover/listenbrainz/playlist/{id}) + Download/Sync in the shared modal. ListenBrainz sync uses
its own -sync-total/-sync-matched status spans, so the mix carries a matching statusHtml; the sync
button id (discover-lb-playlist-{id}-sync-btn) lines up so startListenBrainzPlaylistSync drives it.
The old eager loadTracksForPlaylists calls are now harmless no-ops (their -playlist containers are
gone, so loadListenBrainzPlaylistTracks early-returns). Wing-It is omitted from the card modal for now
(its dropdown needs modal-aware positioning).
Browse by Genre removed (section markup + the loadGenreBrowserTabs call): it was empty
(/api/discover/genres/available returns nothing) and redundant with the Genre Explorer pills.
64 script-integrity tests green.
