/* ═══════════════════════════════════════════════════════════════════════════
   Cisgenics Identity — Auth Splash Treatment (SCRUM-1074)
   Continues the webapp's pre-login SSO splash aesthetic on every Account
   page: dark teal gradient + dot pattern, big white heading, gradient-green
   CTA buttons, white language pill. No card, or a barely-there one.

   Sampled from vnv-cisgenics-web (branch: development, not yet on
   preproduction) — src/features/auth/components/AuthLayout.tsx and
   Login.tsx (commit 47e379579, "redesign login UI with SSO countdown
   modal"). Colors/keyframes below are copied verbatim from that source.

   Loaded after identity.css in _Layout.cshtml. _AdminLayout.cshtml never
   links this file, so nothing here reaches the Admin panel.

   html { font-size: 14px } (see identity.css) — all sizes here are px,
   never rem, to avoid accidental scaling.
