notes: >-
  Relying parties authenticate with the OAuth 2.0 / OpenID Connect Authorization
  Code Grant. The authorization request is carried either as a signed JWT request
  object on GET /auth or, preferably, via a back-channel Pushed Authorization
  Request (POST /auth/par); require_request_uri_registration and
  request_parameter_supported are both true. Clients authenticate to the token
  endpoint with private_key_jwt (a client assertion signed by the RP's RSA key,
  published at the RP's own JWKS URL) or client_secret_post/basic. id_tokens are
  signed RS256. Verified claims are retrieved from GET /userinfo with the bearer
  access token. Production issuer/endpoints are provisioned at partner onboarding.
