notes: >-
  Storefront browsing and UCP catalog reads are unauthenticated. Authenticated
  customer-account access (orders, membership, and the customer-account MCP API)
  uses Shopify Customer Account OAuth 2.0 / OIDC with PKCE (S256). Agent checkout
  is gated on buyer approval rather than an agent-held credential.
