How mosh-hamedani/spring-api-finished works

This is a Spring Boot e-commerce REST API. The documented customer journey is browsing products, creating and filling a cart, registering and logging in, checking out through Stripe, then receiving an order-status update through a webhook and viewing order history. The graph also shows the user, product, cart, and order service/repository layers. Relationships are limited to those shown in excerpts, the source index, or README; some controller and security implementation details were not sampled.
