  # PR-only validation that every provider Dockerfile + build context still
  # builds, before the split sync ever reaches a mirror. Each provider is a
  # self-contained build context (providers/<name>/). These builds are NEVER
  # pushed here — provider images are published per-provider, stamped with the
  # provider's own version, by provider-release.yaml on a `providers/<name>/v*`
  # tag. (Publishing here would tag provider images with the hub version.)
