/* Admin console for the Work Package Suite.
   Browser-side diagnostics + tests that call the same /api on this host.

   ACCESS: the console is gated on the signed-in user's ROLE. auth-guard.js
   already requires a login (redirecting to login.html otherwise) and publishes
   window.WP_USER; here we show the console only when that user is an admin, and
   show an "Admins only" notice otherwise. Every user-management API is also
   enforced as admin-only server-side, so this is a real gate, not obfuscation. */
