  # Pinned to the provider CSI class, NOT left to the DefaultStorageClass
  # admission plugin: our clusters always carry TWO default-annotated classes
  # (k3s' node-local `local-path` and the provider's own CSI class), and with
  # two defaults the plugin picks the newest by creationTimestamp. Unpinned,
  # redis' data landed on node-local disk on the unlucky flip, the PV's node
  # affinity pinned redis to that node, and the data died with it — silently,
  # since redis comes up Ready either way. Same defect #234 fixed for the
  # Supabase PVCs.
  # Resolved to a real class BEFORE apply by renderK8sStorageClassPlaceholder
  # (storageClassName is immutable once the PVC exists, so it cannot be patched
  # afterwards).
