note: >-
  The harvested spec declares no securitySchemes because Greater Bank's public
  CDR Product Reference Data endpoints are unauthenticated by design. The
  broader CDR consumer-data-sharing tier (not part of this public spec) is
  secured under the accredited-data-recipient model with OAuth2 + OpenID Connect
  on the FAPI profile via the CDR register.

      (authorization/token). Documented via the CDR regime, not exposed as a
      self-serve public developer OAuth surface. Not independently probed.
