How to support UCP on Shopify

In short

Shopify merchants do not build UCP: Shopify serves it. Turn on Agentic Storefronts in Admin, keep your catalog data clean, and check that /.well-known/ucp answers on your domain. Agents register their own profiles; you control which channels sell from Admin.
