+#### Enable signed requests

+```bash
+zenstack-proxy --studioAuthKey "MCowBQYDK2VwAyEAFSJV7wjdFuDz2CqYX7hGnITQvcmJYy7OJQq2Cy2Eiqs="
+```
+
+When `--studioAuthKey` is provided, every incoming request must include an `X-ZenStack-Signature` header in the format `t=<unix timestamp>,v1=<base64url signature>`.
+The signed message format matches ZenStack Studio: `payload + timestamp [+ authorizationToken]`.
+
+- For `GET` and `DELETE` requests, `payload` is the raw query string without the leading `?`.
+- For body-based requests, `payload` is the exact JSON request body string.
+- For requests without query params or a request body, `payload` is an empty string.
+- If an `Authorization: Bearer <token>` header is present, append `<token>` to the signed message.
