/* =========================================================
PAGE HERO FALLBACK BACKGROUND
=========================================================
   The base .page-hero rule (in the minified block above) sets
   `color: #fff` because rich heroes (.page-hero-media +
   .page-hero-overlay) provide a dark image background. Pages
   that don't use the media pattern — currently /courses/player.html —
   inherit `color: #fff` but land on the body's light background,
   making the title + subtitle invisible.

   This rule adds the same teal gradient the bursaries + marketplace
   modules ship as their hero background, applied at the .page-hero
   level so the white text always has contrast. When .page-hero-media
   IS present, it sits at z-index:0 with `position:absolute; inset:0`
   and paints over this background — so rich heroes are unaffected.
