   DXED ARENA: MISSION AUDIO (menu music player)

   Reads as shell instrumentation, not a media widget: dark compact
   surfaces, hairline technical borders, sharp 2px corners, restrained
   amber accent (the shell's selection color), cyan only for the live
   signal. Desktop: the dock sits inline in the footer line; the track
   list opens as a compact panel anchored above it. Mobile
   (body.dx-music-m): the dock re-docks as a slim strip above the
   bottom nav and the list becomes a bottom drawer.
