  * Probe Traefik/Authelia protection on /admin.
- * Returns true only when a same-origin GET succeeds (HTTP 200),
- * meaning the visitor is already authenticated for admin.
- * Failures (401/403/302/network) keep the public site admin-free.
+ * Returns true only when:
+ *  1) GET /admin succeeds (HTTP 200) — path is allowed through Authelia
+ *  2) GET /api/v1/admin/me succeeds — Remote-User is present and authorized
+ *
+ * (2) matters on LAN where Authelia may bypass auth but still leave no Remote-User,
+ * so the public site stays admin-free for anonymous visitors.
