  Derived from the live member-authentication OIDC discovery document. This is
  the identity-provider surface used for member sign-in (Umbraco member-auth
  delivery API), NOT authentication for a public banking/data API — Coast Capital
  publishes no public first-party API. Recorded here because it is a real,
  anonymously-fetchable auth surface.
