/* ==========================================================================
   auth.css — shared chrome for the standalone auth / funnel pages
   (login, request-access, forgot/reset password, accept-terms, security,
    join, change-password, logout).

   Linked AFTER global.css by each of those pages. This replaces the ~150-line
   <style> block every one of them used to duplicate (same reset, body,
   geometric background, top-nav, card, form, buttons, footer). One source of
   truth -> the pages render provably identically, and the navy surfaces are
   centralized here so a future light theme can override them in one place.

   Selectors mirror the classes the pages already use (card container comes in
   three flavours: .login-container / .form-container / .card / .logout-container;
   header as .login-header / .form-header / .card-header) so this is a drop-in
   replacement — no markup renames required. Reuses global.css tokens; gold
   accents stay literal (theme-independent), navy surfaces use tokens.
   ========================================================================== */

       light mode" bug (2026-06-28), patched by the re-assert block below. The
       durable fix (rename to --auth-* and update usages) is tracked in the UI
       polish plan Phase 7; until then, any NEW token here must be --auth-*-named. */
