Checkout

Checkout will require customers to sign up or sign in before purchase so subscriptions and licence ownership can be attached to a verified account; guest purchase is intentionally not supported.

Anonymous cart creation can remain available before sign-in
Purchase must require sign up or sign in
The canonical cart must survive auth return and be associated on the server with the verified customer account before order creation
This site does not yet have verified sign-in, callback, customer ownership mapping, or authoritative order/subscription/licence sources wired
Until those contracts exist, this page remains a non-purchasing shell and must not imply a working guest checkout
