## Overview

The repository appears to be a Malay-language library-system web app, with pages for duty scheduling, attendance, reports, and administration. The README provides no workflow details, and the sampled source covers only Firebase setup and generic Firestore helpers; page-to-page navigation and page-to-data calls therefore cannot be confirmed. The diagram preserves the distinct capabilities named by the page files without asserting those connections.

Main entry points: [`src/firebase.js`](https://github.com/yeewei09101/library-system/blob/main/src/firebase.js) (Firebase setup), [`src/db-helper.js`](https://github.com/yeewei09101/library-system/blob/main/src/db-helper.js) (Firestore helpers), [`src/index.html`](https://github.com/yeewei09101/library-system/blob/main/src/index.html) (Sign-in)
