  Board exposes a live agent-commerce MCP server via Shopify's Universal Commerce
  Protocol (UCP). The MCP endpoint is advertised in /.well-known/ucp and in
  /llms.txt. Discovery requires a UCP agent profile URI; checkout requires
  contemporaneous human buyer approval. This is a Shopify-platform-provided
  surface bound to the board.fun store, not a bespoke first-party server.
