/* =============================================================================
   Save Shelf - hub-wide sticky bar holding up to 3 cached world+character save
   pairs. Browser-only (IndexedDB); all hub tools read the active slot from it.

   States:
     collapsed (normal) - header strip + a row of 3 slot chips (noticeable).
     collapsed (compact) - header strip only; used on the map + depot previews.
     expanded            - header strip + the full 3-slot management panel.

   Colour vars fall back to literals so the shelf works on any hub page.
