/* ═══════════════════════════════════════════
   MUSIC — Floating Spotify Player
   The FAB and panel chrome are fully bespoke, stacked directly above
   the existing notif-fab. The iframe Spotify injects inside
   .music-panel-embed (see js/music.js) keeps its own native controls —
   a cross-origin document we can't restyle — but theme=0 on the embed
   URL picks Spotify's dark theme so it blends in as closely as an
   embed allows.
