notes: >-
  The Android/Google API base hosts (androidmanagement.googleapis.com, etc.) do
  not serve /.well-known/ discovery documents (all 404). OAuth/OIDC discovery for
  these APIs is served by Google's shared identity host accounts.google.com, and
  Google's org-wide security.txt is served from www.google.com.
