/* ==========================================================================
   Guardian Moldova — Landing page custom styles (Web-03 redesign)
   ==========================================================================

   Modern FinTech / Bento-Grid aesthetic.
   Tailwind (CDN) handles layout/spacing/typography utilities.
   This file adds only what Tailwind cannot express cleanly:
     - ambient mesh glow backgrounds
     - glassmorphism surfaces (light + dark)
     - gradient text + glow borders
     - phone mockup realism (frame, dynamic island, glass sheen)
     - floating alert badge
     - bento card hover lift + glow
     - timeline glowing connector
     - FAQ +/- icon rotation
     - custom scrollbar
     - language pill active state
     - accessibility (reduced motion, focus-visible)

   Brand palette (DEC-039 + Web-03 brief):
     --abyss:    #090D16  (deep navy-black hero/dark sections)
     --slate-900:#0F172A  --slate-800:#1E293B
     --emerald:  #10B981  --emerald-600:#059669
     --sapphire: #3B82F6  (family blue)
     --amber:    #F59E0B  (soft warning)
     --bg-light: #F8FAFC  --bg-mid:#EEF2F6
