/* ============================================================================
   auth.css — Shared styling for all identity pages (login, register, forgot/
   reset password, confirm email, 2FA, access denied, lockout).

   Design: modern enterprise split-screen — polished light form panel + dark
   brand showcase that renders a LIVE PREVIEW of the real student dashboard,
   built with the same design vocabulary as student-dashboard-modern.css
   (glowing stat cards, streak card, progress ring, certificate, live pill).

   Colors come ONLY from the dynamic brand pipeline (_DynamicBrandColors injects
   --primary*, --secondary*, --bs-primary-rgb, --shadow-* over brand-identity.css
   defaults). Brand-derived tokens use color-mix() with a static fallback on the
   line above for old engines.

   RTL: CSS logical properties throughout so the split panel and controls mirror
   automatically under dir="rtl".
