notes: >-
  Google Cloud API service hosts (e.g. cloudresourcemanager.googleapis.com,
  storage.googleapis.com) do not serve a /.well-known discovery surface. OAuth
  2.0 / OIDC discovery is served centrally from accounts.google.com, and the
  RFC 9116 security.txt is served from the corporate google.com host.
