/* ==========================================================================
   GH Analytics — Front Page + Navbar Theme (v3)
   --------------------------------------------------------------------------
   v3 changes:
   - Reduced decorative background noise (subtler orbs, removed grain)
   - Replaced heavy glassmorphism with solid-ish surfaces
   - Tightened typography: smaller headline, compact above-the-fold
   - Added: hero-header, hero-freshness, hero-search-kbd,
     hero-alerts, keyboard-active result state
   - WCAG AA contrast verified on text/background combos
   - Consistent tile styling; chevrons removed for cleaner feel
