## Overview

STON Placement App is a student-facing placement-drive mobile app. Students log in, browse and filter drives by eligibility, inspect a drive and apply, then review application statuses and open a QR admit card. The app uses local mock student/drive data and React Context for shared applied state; the separate Express mock API provides equivalent server endpoints but the README says the mobile app does not call it. Screen-level detail and admit-card wiring are represented from documented features; those screen implementations were not sampled.

Main entry points: [`src/navigation/AppNavigator.js`](https://github.com/jayant134/ston-assignment-jayant/blob/main/src/navigation/AppNavigator.js) (Screen Navigation), [`src/screens/DriveListScreen.js`](https://github.com/jayant134/ston-assignment-jayant/blob/main/src/screens/DriveListScreen.js) (Drive Listing), [`src/screens/MyApplicationsScreen.js`](https://github.com/jayant134/ston-assignment-jayant/blob/main/src/screens/MyApplicationsScreen.js) (My Applications), [`src/context/AppContext.js`](https://github.com/jayant134/ston-assignment-jayant/blob/main/src/context/AppContext.js) (Application State)
