/* ============================================================
   FOUND BHUTAN - hero.css
   Location: /assets/styles/hero.css
   Loaded only on: index.php (homepage)

   Contains ALL hero-related styles, previously split between:
     1. The two conflicting .hero blocks in main.css (removed)
     2. The inline <style> block in index.php (removed)

   The .nb-* classes are scoped to the new hero redesign.
   The legacy .hero-overlay and .centered rules are kept here
   in case any other include still references them - safe to
   delete once confirmed unused.
