Overview

Once browsing is stable, the path moves into cart state, cart persistence, and checkout. Providers are introduced before pages depend on them, product detail upgrades to add-to-cart only after the cart context exists, and checkout success uses a deliberately minimal order-reading surface so learners only build what that unit needs.
