  # ReadWriteOnce for k3d/local-path compatibility.
  # NOTE: k3d uses the local-path provisioner which only supports RWO.
  # For production with multiple concurrent writers (workers + history server),
  # replace with a RWX-capable storage class such as NFS or Longhorn and
  # change accessModes to [ReadWriteMany].
