/* ============================================================
   DIGIRA FEST S1 — REGISTRATION PORTAL
   Served independently from https://register.digira.xyz/
   Self-contained: no dependency on the main site's stylesheets.

   Priorities: fast first paint, large touch targets, clear focus
   states, minimal motion. Same Digira design language as the
   main site (dark shell, neon blue/purple, cut corners).
