summary: >-
  Brooklinen serves RFC 8414 OAuth 2.0 authorization server metadata at its store origin, pointing at the
  Shopify customer account issuer for shop 9517126 and fronted on account.brooklinen.com. Four scopes are
  advertised. These govern customer account access — including the Customer Account MCP API — not a developer
  API program; Brooklinen operates no partner/developer OAuth application surface of its own.

notes:
- No scope-by-scope reference page is published by Brooklinen; scope semantics follow Shopify's Customer
  Account API documentation.
- The storefront UCP/MCP endpoint at /api/ucp/mcp is gated by agent identity (UCP agent profile), not by
  OAuth scope. See authentication/brooklinen-authentication.yml.
