+# CloudNativePG Operator for ringtail k3s cluster
+# Deploys the operator only; PostgreSQL clusters are created separately
+#
+# Sibling of cloudnative-pg.yaml (minikube). Same mirror, same release,
+# different destination. Both apps will coexist during the immich
+# migration; the minikube one is removed at the end of the broader
