## Overview
This repository contains a Spring Boot user-management application, presented in the README as a sample web app with MySQL storage. Users can manage accounts through REST endpoints or a browser-based interface; authentication loads user records and role data. The main internal layers are controllers, services, repositories, and JPA entities. The source excerpts show controller-to-service and authentication-to-repository interactions, while the README documents MySQL use. Security configuration and several auxiliary controllers are present in the tree but their wiring was not sampled.
