/* ==========================================================================
   أرباحي — Public Footer (Task ID: A — SUBTASK A2)
   --------------------------------------------------------------------------
   Modern, professional, glass-effect footer that matches the homepage's
   dark + purple-gradient aesthetic. Linked from public_header.php AFTER
   landing.css so it can override the legacy `.landing-footer` rule.

   Design system (matches worklog.md):
     • Bg: linear-gradient(180deg, #0a0a14 → #13131f)
     • Top border: 1px solid rgba(108,92,231,0.15)
     • Glass: backdrop-filter: blur(12px) saturate(140%)
     • Text primary #f5f5fa · secondary #b8b8c8 · tertiary rgba(245,245,250,0.5)
     • Border: rgba(255,255,255,0.08)
     • Primary #6c5ce7 → primary-light #a29bfe (135deg gradient)
     • Radii: 12px (cards), 10px (buttons), 999px (pills)
     • Cairo + Tajawal (Arabic), Inter (Latin)
