mohitsharma2635/chessVision — reverse-engineered prompt

Build me a polished mobile app called ChessVision in this Expo project. The README is still the default starter, so use the project name as the guide and turn it into a clean chess scanning app.

I want a home screen that explains the idea, a simple way to take or choose a photo of a chess board, and a results screen that shows the photo, a chess board preview, and a readable list of detected pieces or a placeholder result if real detection is not set up yet. Make it feel like a real first version, not just starter screens. Add nice styling, clear empty states, loading states, and friendly error messages.

Keep it simple enough to run on Android, iOS, and Expo Go. Use the existing TypeScript Expo setup and app folder. If you need current Expo docs, look them up online. Make sure it runs cleanly with npm install and npx expo start.
