## Overview

This is a React water-monitoring dashboard, not a backend service: users enter through a demo login and then view water-system status, controls, alerts, trends, schedules, and activity history. The Dashboard owns API requests and state, then passes data and callbacks to display components. Login currently creates a frontend-only token; the excerpts do not show real authentication or backend implementation. The README is a Vite template and documents no product capabilities, so the domain map is based on the sampled source; unshown Dashboard behavior is not expanded beyond its visible features.

Main entry points: [`src/pages/Dashboard.jsx`](https://github.com/ejine0727/water-monitoring-frontend/blob/main/src/pages/Dashboard.jsx) (Dashboard state and API), [`src/App.jsx`](https://github.com/ejine0727/water-monitoring-frontend/blob/main/src/App.jsx) (App auth gate), [`src/pages/LoginPage.jsx`](https://github.com/ejine0727/water-monitoring-frontend/blob/main/src/pages/LoginPage.jsx) (Demo login), [`src/styles/index.js`](https://github.com/ejine0727/water-monitoring-frontend/blob/main/src/styles/index.js) (Shared styles)
