## Overview

Stock Manager is a browser-based inventory app. Users manage products and categories, adjust stock, and inspect inventory status and value; Firestore listeners keep the displayed data current. The excerpts show the app’s Firestore and authentication calls, while the README documents search, filtering, and low-stock alerts. The graph groups those capabilities under the app because their implementation details were not all sampled; the rules file’s exact behavior was also not inspected.

Main entry points: [`app.js`](https://github.com/sujanirig-web/stock-manager-/blob/main/app.js) (Inventory interface), [`firebase.js`](https://github.com/sujanirig-web/stock-manager-/blob/main/firebase.js) (Firebase setup), [`helper.js`](https://github.com/sujanirig-web/stock-manager-/blob/main/helper.js) (UI and data helpers), [`firestore.rules`](https://github.com/sujanirig-web/stock-manager-/blob/main/firestore.rules) (Firestore rules)
