/* ============================================================
   App shell look — sidebar, queue drawer, player bar.
   Transferred from the ModernSK Music design reference and layered on
   top of modern-sk's tokens + component CSS. Only layout + product
   classes live here; every colour/shadow/radius flows from modern-sk
   tokens so the whole shell restyles from one place (and stays in sync
   with a future Flutter client sharing the same tokens).

   Icons are @phosphor-icons/react <svg> elements carrying className "ph";
   they size to 1em, so font-size here controls them like the reference.
