+:::tip Behind a reverse proxy
+When serving the admin from a different public origin (domain, host, or port) than the API, set `host`/`port` accordingly and ensure your proxy forwards headers (e.g., `X-Forwarded-*`). If the admin is reachable at a different origin, prefer configuring that origin explicitly.
