 Secrets guidelines:
 
-- **Clerk auth is required for now**: you must configure Clerk keys/JWKS for the app to work.
-- Never commit Clerk secret key.
+- Choose auth mode explicitly:
+  - `AUTH_MODE=local`: set a strong `LOCAL_AUTH_TOKEN`
+  - `AUTH_MODE=clerk`: configure Clerk keys
+- Never commit `LOCAL_AUTH_TOKEN` or Clerk secret key.
 - Prefer passing secrets as environment variables from the host (or use Docker secrets if you later
   migrate to Swarm/K8s).
 - Rotate secrets if they ever hit logs.
