/* 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 API this page calls is also
   enforced as admin-only server-side, so this is a real gate, not obfuscation.

   USER ACCOUNTS LIVE ON users.html, not here. They moved when the Project Super
   User role arrived: administering users is no longer an admin-only act, so the
   page that does it can't be behind an admins-only gate. What stays here is what
   genuinely is app-wide and admin-only — settings, feature flags, diagnostics,
   project archiving, and the default-member rule for future projects.

   Shared helpers (api, uesc, jsq, the role vocabulary) come from console-util.js. */
