  There is no OpenAPI to derive scopes from and Arlettie publishes no scopes reference page. This is
  the verbatim scopes_supported array from the live RFC 8414 authorization-server metadata served by
  the Les échappées storefront. Descriptions below are labelled by origin: two are OIDC-registered
  and carry their standard meaning; two are Shopify customer-account scopes whose meaning is inferred
  from their name and the resource they guard, and are marked as such rather than asserted.

  description: Release the customer's email and email_verified claims.
  description_origin: oidc-core-registered
  flows: [authorizationCode]
  sources: [well-known/arlettie-oauth-authorization-server.json]
- scope: customer-account-api:full
  description: Full access to the authenticated customer's account API surface (orders, addresses,
    profile) for this shop.
  description_origin: inferred-from-scope-name
  flows: [authorizationCode]
  sources: [well-known/arlettie-oauth-authorization-server.json]
- scope: customer-account-mcp-api:full
  description: Full access to the authenticated customer's account surface through the MCP transport
    — the customer-scoped counterpart to the anonymous UCP/MCP endpoint.
  description_origin: inferred-from-scope-name
  flows: [authorizationCode]
  sources: [well-known/arlettie-oauth-authorization-server.json]
  note: >-
    Notable: this shop advertises an MCP-specific OAuth scope, which is what distinguishes the
    anonymous agent surface (catalog, cart, checkout) from a customer-authorized one (orders,
    saved addresses, account history).

summary:
  scope_count: 4
  granularity: coarse
  note: >-
    Both non-OIDC scopes are ":full" — there is no read/write or per-resource split, so a customer
    authorizing an agent grants the whole account surface or nothing.
