/* ==========================================================================
   Rectangle One — course listing (Category / Search / All Courses)
   --------------------------------------------------------------------------
   Restyles the default theme ".course-item" listing into the homepage card
   system: a thumbnail with price + level overlays, an eyebrow category label,
   a meta row and a footer CTA. Also adds a category hero header and a sticky
   filter sidebar. Uses the tokens from r1-theme.css.

   Loaded only on listing pages (see search.blade.php).
