note: >-
  No OpenAPI exists in this repo, so this profile is not derived from securitySchemes. It is read
  verbatim from the RFC 8414 authorization-server metadata and RFC 9728 protected-resource metadata
  that www.wayup.com serves for its MCP endpoint. Yello Enterprise tenant sites (customer.yello.co /
  customer.recsolu.com) are not covered - their authentication model is not publicly documented.
