## Overview

星味外卖 is a teaching takeout-management application. Its documented current workflow is an administrator using the web console to log in and manage employees, categories, and dishes, with paging, search, editing, and status changes; the console also presents a business overview and maintains login state. The backend is documented with H2 and MySQL options and Swagger documentation. No source excerpts were provided, so the graph is limited to README-supported capabilities and broad relationships; it does not assert unverified controller-to-service or service-to-mapper calls.
