/* =========================================================================
   studio.css — Skin Studio: deck | living stage | channels.
   Loaded only by studio.html. No raw colour literals: theme tokens only.

   TWO COLLISIONS RESOLVED (both were silent in the donor):
     1. `.tabs [role=tab]` here vs `.tabs button` in site.css. Both matched the
        same buttons on this page; the winner was decided by link order, not by
        intent. The studio lane is `.studio-tabs [role=tab]` now.
     2. `.card { padding: 16px }` was declared here with NO page scope, so this
        sheet silently reshaped the shared card component. It is
        `.card.studio-card` now — an opt-in, applied in the fragment.
   `.panel-label` also meant something different in map.css; this one is
   `.studio-panel-label`.
