  Authorization Code + PKCE (S256) against an Okta-hosted custom authorization
  server. private_key_jwt client authentication is supported, which is the
  FAPI-grade confidential-client method appropriate for the institutional B2B
  audience. Business scopes (aor.role, api.read, interclient_access) are captured
  in scopes/northern-trust-scopes.yml. Live API access requires partner
  registration; only the anonymous discovery metadata is public.
