Simple check-in page that automatically captures a photo every 15 seconds and uploads it to the server.

• Node.js 18+ (you already have Node 22)

npm install

npm start

Then open:

http://localhost:3000

The browser will ask for camera permission. Allow it, and the app will take a photo immediately, then every 15 seconds.

• Photos are saved on the server in the project folder as photo_*.png.
• Check-ins are stored locally in your browser (localStorage).
