   ChloeZ Marketplace — marketplace.css
   Loaded alongside index.css (course cards, tooltip hover-preview, nav,
   footer — all reused verbatim, same classes, same JS interaction ported
   from assets/js/index.js) and about.css (mobile nav drawer). Everything
   in THIS file is new to the marketplace page specifically: the hero
   search, filter bar, results grid wrapper, and the fullscreen overlay.
   Uses the exact same design tokens as index.css/about.css/admin.css —
   no new colors introduced.
