/* ---------------------------------------------------------------------------
   Marketplace-specific styles — hero, "browse by category" tiles, listing
   grid/cards, and the detail modal. The page header/footer chrome comes from
   site.css/site.js (identical to every other page); this stylesheet only
   adds the marketplace-specific structural CSS on top of it.

   Every --mkt-* token below is an alias onto site.css's shared design tokens
   (--accent, --purple, --border, --text, --text-dim, --bg, --bg-elev,
   --radius, --green) so this file's colors stay in sync with the rest of
   the site automatically if those tokens ever change. Gold star ratings are
   the one intentional exception — a universal rating convention kept as-is.
