+# Development override: bind-mount local Angular build output directly
+# into the gateway container. Eliminates the need for volume copy + restart
+# after every `ng build`.
+#
+# Usage:
+#   docker compose -f docker-compose.stella-ops.yml -f docker-compose.dev-ui.yml up -d stellaops-router-gateway
+#
+# Then just run `ng build --configuration=development --watch` and refresh the browser.
