/**
 * PromotionsModule — boundary declared, implementation pending.
 *
 * Owns (exclusively): `promotions`, `promotion_rules` — milestone 3
 *
 * Automatic, cart-level discounts. Pricing is calculated in one place so storefront, admin and invoices can never disagree.
 *
 * Anatomy once implemented (see ../README.md):
 *   promotions.module.ts        wiring only
 *   promotions.controller.ts    HTTP surface, no logic
 *   promotions.service.ts       business rules
 *   promotions.repository.ts    the only file that touches Prisma
 *   dto/                           request/response shapes
 *   public/                        what other modules may import
