## Overview

This repository implements a hostel complaint-management application: students submit and track issues, while wardens and administrators have dashboard, user-management, and analytics screens. The sampled flow confirms complaint submission from the frontend through its API client to the backend, where services validate and persist data. The README is empty and most frontend pages and security configuration were not sampled, so their internal request wiring is not shown.
