 * CheckoutModule — boundary declared, implementation pending.
 *
 * Owns (exclusively): Checkout sessions (Redis, short TTL)
 *
 * Orchestrates the cart → stock reservation → payment intent → order transition. The only module allowed to coordinate across contexts, and it does so through public services and events.
 *
 * Anatomy once implemented (see ../README.md):
 *   checkout.module.ts        wiring only
 *   checkout.controller.ts    HTTP surface, no logic
 *   checkout.service.ts       business rules
 *   checkout.repository.ts    the only file that touches Prisma
 *   dto/                           request/response shapes
 *   public/                        what other modules may import
