notes: >-
  Google Cloud authenticates with OAuth 2.0 access tokens minted for either an
  end user (3-legged) or a service account (2-legged, via signed JWT or
  Application Default Credentials / Workload Identity Federation). The optional
  API key (query `key`) only identifies the calling project and does not grant
  authorization. OIDC discovery confirmed live at accounts.google.com (200).
