## Overview

This is a small React to-do app. The main workflow is entering a timed task, managing it as pending or complete, and viewing completion progress. Task state, countdowns, reminders, greetings, and chart rendering are implemented together in `src/App.js`; the README also describes responsive styling. The sampled source confirms alarm audio is loaded from an external URL. Unsampled styling details and the README’s claimed confetti and notification capabilities are not mapped as separate components.

Main entry points: [`src/App.js`](https://github.com/dbger01/react-startup-todo/blob/main/src/App.js) (Task management), [`src/index.js`](https://github.com/dbger01/react-startup-todo/blob/main/src/index.js) (React entry)
