/*!
 * SonicHQ — shared music CSS (track cards + fixed player)
 * ---------------------------------------------------------------------------
 * Skin-agnostic. Every colour reads from a --trk-* / --plr-* custom property
 * with a built-in fallback, so this file renders correctly on its own even in
 * a skin that defines no tokens.
 *
 * To brand the music section for a skin, add a token block to that skin's
 * stylesheet (see the block at the top of style.css for a worked example).
 * Load order does not matter: the token blocks are scoped to
 * .soundtracks/.shq-player/.track-single and always beat these fallbacks.

   MUSIC — TRACK CARDS & FIXED PLAYER
   -----------------------------------------------------------------------------
   Structure is shared across all three skins; every colour comes from the
   --trk-* / --plr-* tokens defined above, so each stylesheet can restyle the
   whole music section by changing that one block.
