/*
  MUSIC
  =====
  "Calm, comfortable, welcoming... belongs inside this world rather than
  sitting on top of it." This reuses the same bounded, centred overlay
  panel every other diegetic surface in the workshop uses (see
  css/overlays.css) — just sized roomier, since browsing a real library
  needs the space a pinboard or notebook doesn't. The material itself reads
  as a built-in cabinet radio: a dark wood shell, a warm paper browsing
  surface (matching the notebook/pinboard's own paper tone), brass controls.
  Nothing here tries to look like Spotify or Windows Media Player.
