+/// Add annotations via `values_overrides` depending on your distribution:
+/// - NGINX: `nginx.ingress.kubernetes.io/backend-protocol: GRPC`
+/// - OpenShift HAProxy: `haproxy.router.openshift.io/*` or use OpenShift Routes
+/// - AWS ALB: set `ingress.controller: aws`

+/// # Database credentials
+/// CNPG creates a `<cluster>-superuser` secret with key `password`. Because
+/// `envVarsSecret` injects secret keys verbatim as env var names and the CNPG
+/// key (`password`) does not match ZITADEL's expected name
+/// (`ZITADEL_DATABASE_POSTGRES_USER_PASSWORD`), individual `env` entries with
+/// `valueFrom.secretKeyRef` are used instead. For environments with an
+/// External Secrets Operator or similar, create a dedicated secret with the
+/// correct ZITADEL env var names and switch to `envVarsSecret`.
