   AuthModal — Substack-style sign-in / register modal.
   Used by AuthModalViewComponent. Theme tokens come from the
   host app's stylesheet (--bg-elevated, --text-primary, etc.).

   Per Sidekick UI convention: --border-secondary (not -primary)
   inside elevated surfaces, since elevated bg ≈ border-primary
   in some themes (Ember Dark).
