   public/auth/auth.css — Shared styling for the auth pages.
   ---------------------------------------------------------------------------
   Used by login.html, forgot.html, reset.html. Deliberately decoupled from
   the main SPA stylesheet (style.css + style/*.css) so unauthenticated
   pages don't pull in the full UI bundle. Inlined-feel layout: small card,
   centered, brand logo strip on top.
