  No first-party OpenAPI is published, so this profile is read from Soylent's
  live OIDC / OAuth 2.0 authorization-server discovery documents. Authentication
  is Shopify Customer Accounts: OpenID Connect + OAuth 2.0 Authorization Code
  with PKCE (S256). The storefront / UCP MCP read tools need no auth; transacting
  requires buyer-approved authorization.
