  The only OAuth surface Willow serves is Shopify Customer Accounts on its own account.onewillow.com
  host. Its RFC 8414 / OIDC metadata declares four scopes. Willow publishes no scope reference page
  of its own; the descriptions below are read from the scope names and the discovery document, and
  are marked as such.

notes:
  - >-
    The anonymous UCP commerce MCP endpoint (https://onewillow.com/api/ucp/mcp) is NOT scope-gated —
    it gates on a UCP agent profile URI and, for order reads, an agent JWT. See
    authentication/willow-authentication.yml.
