   [NE:muse] MUSE STUDIO — conversational Panel Studio styles
   =====================================================================================
   @narroengine  subsystem: Muse (chat surface)
   @related      muse-studio.js (markup), adv-system.css (--adv-* tokens — already
                 re-declared under body.narrorift-mode, so dark theme is automatic),
                 index.php #muse-studio-root + .adv-ps-classic.
   Simple mode: the root is [data-adv] (ui-modes.css hides it) and the classic
   composer renders exactly as before — the .adv-ps-classic collapse below is
   scoped to html[data-ui-mode="advanced"] only.
