 - Cart, checkout, and pricing runtime records are not seeded; only deterministic tax, shipping, and discount configuration is seeded. Runtime carts/checkouts are created by services and tests.
 - Checkout completion intentionally stops before order creation in this slice. `CheckoutService::completeCheckout()` is a Phase 5 boundary until order, payment, and fulfillment tables/services exist.
+- The cart drawer reads the current session/customer cart without creating an empty cart on every storefront render; carts are created on first add-to-cart or checkout/cart service mutation.
