## Overview

This is a small Spring Boot product API. Its visible workflow accepts product-list or fixed-ID GET requests, delegates through ProductService to the selected Fake Store implementation, and returns DTO-shaped responses. The ID lookup calls Fake Store; list retrieval currently returns null, and create, update, and delete are unimplemented. No persistence layer or additional product capabilities are evidenced. The graph reflects the sampled source; the README is empty.
