Argo CD — app-of-apps children

noble-root syncs this directory. Keep one child Application (noble-platform) so the UI does not list every Helm release separately.

noble-platform.yaml — one Application with multiple sources: Helm charts from upstream repos plus a Git ref: values entry that supplies $values/.../values.yaml and path: clusters/noble/apps for plain Kustomize (namespaces + extra YAML only). No kustomize --enable-helm required.
