  Derived from the live OIDC / RFC 8414 discovery documents served at liveouter.com, not from
  an OpenAPI (Outer publishes none). The authorization server is Shopify's Customer Account
  API issuer for shop id 11846615098, fronted on Outer's own account.liveouter.com host.
  The UCP MCP endpoint at /api/ucp/mcp uses a different gate: it requires a resolvable UCP
  agent profile URI rather than an OAuth token, and buyer payment approval on top.
