+## Summary
+
+Deliver `@suaveplan/api-plugin-store` on the genesis branch from scratch at enterprise quality. E-commerce plugin: product catalog (CRUD + variants + images), categories, inventory bridge to `@suaveplan/api-plugin-inventory`, cart (add/update/remove/clear), checkout (create order + payment intent bridge to `@suaveplan/api-plugin-payment`), order lifecycle (pending → confirmed → shipped → delivered → returned), and a basic discount/coupon engine. Routes under `/store`. Per-table SurrealQL. Typed events: `store:order:created`, `store:order:shipped`, `store:cart:abandoned`. Auth-gated write paths; public read paths for product catalog.
