Architecture
Layered MVC Monolith
Browser and API requests pass through controllers, service contracts and implementations, and JPA repositories into PostgreSQL. Catalog, cart, order, invoice, and recommendation areas share security, DTO, exception, and event infrastructure. WebSocket handles real-time updates, while email and document adapters support background output flows.
