   Phase 2 · Page hero templates                       S.MONK 2026-04
   ══════════════════════════════════════════════════════════════════
   Five hero templates that every non-homepage public page uses.
   The homepage's hero (.home-hero) is owned by Phase 1A and stays
   distinct.

     A  Content / guide hero       — class .page-hero.ph--content
     B  Tool / reference hero      — class .page-hero.ph--tool
     C  Course detail hero         — class .page-hero.ph--course
     D  Sales / conversion hero    — class .page-hero.ph--sales
     E  Auth / form hero           — class .page-hero.ph--auth

   All five share the same navy gradient and the same nav offset.
