summary: >-
  binske publishes no first-party authentication documentation. The one
  authenticated surface on a binske-controlled host is the Shopify customer
  account OAuth 2.0 / OpenID Connect stack advertised from the storefront's
  well-known metadata, plus an anonymous read path on the UCP MCP endpoint.

  The authorization server is Shopify's, not binske's. There is no binske
  developer authentication page, no key issuance, and no first-party token model.
