The route from "mozimo.in displays Shopify products" to "mozimo.in sells them", as a plan with a phase spine and gates, plus the open decision tickets that still shape it and the evidence they rest on. - .scratch/shopify-headless-commerce/: plan.md (phases and gates), map.md (the wayfinder map), 10 open decision tickets - CONTEXT.md: Storefront / Theme store / Cart / Parity vocabulary - docs/adr/0001-0003: Checkout stays Shopify-hosted, one Variant per product, the checkout domain stays shop.mozimo.in - docs/research/ and docs/shopify-catalog-inventory.md: verified store facts, the Cart API probe, and the catalogue inventory Raw Shopify doc scrapes under .scratch/shopify-research/ are ignored: they are working material, not record.

Question
How is a Cart identified and carried across requests? Shopify addresses a Cart by ID, and this Storefront renders on the server, so the mechanism has to survive both.
Decide: where the Cart ID lives (an httpOnly cookie the server sets, client storage, or both), what its attributes are, and how the client hydrates without a flash of an empty Cart.
Decide the failure paths too, because both are reachable: a Cart expires after 30 days, and Shopify deletes it on checkout completion — so a returning buyer can arrive holding a cookie that points at nothing. What happens then — silent re-create, cleared Cart, or an error?
