Phase 3 of storefront restructure plan - create dedicated modules for e-commerce functionality: - cart: Shopping cart management with storefront API routes - CartItem model with cents-based pricing - CartService for cart operations - Storefront routes for cart CRUD operations - catalog: Product catalog browsing for customers - CatalogService for public product queries - Storefront routes for product listing/search/details - checkout: Order creation from cart (placeholder) - CheckoutService stub for future cart-to-order conversion - Schemas for checkout flow These modules separate e-commerce concerns from core platform concerns (customer auth), enabling non-commerce platforms.
