 `VITE_HCAPTCHA_SITEKEY` in the frontend deployment.
 
+The upstream sample uses plural names for some built-in plugins, but the
+backend expects the singular names shown above. This deployment configuration
+enables all built-in plugins by default. Keep `client-config` separate in
+`external_plugins`.
+
+The deployment patch synchronizes the plugin list from `config/config.json` to
+the stored frontend configuration when the backend starts. Other frontend
+settings in MariaDB stay unchanged. Restart the backend after you enable or
+disable a plugin.
