/* ============================================================================
   CETARCH — shared design system
   Single source of truth for design tokens + shared UI components, consumed by
   BOTH the public portal (layouts/portal.php) and the admin panel
   (layouts/admin.php). Layout-specific rules (sidebar, header, hero, tables,
   forms, …) still live inline in each layout.

   Brand colour is navy (#0F2B4E). The canonical token is --primary; the older
   --teal / .btn-teal / .badge-teal names are kept as ALIASES so existing markup
   keeps working — prefer --primary / .btn-primary / .badge-primary in new code.
