Shared mode setup (Firebase Realtime Database)

1) Create a Firebase project and add a web app.
2) Enable Realtime Database.
3) Copy `firebase-config.example.js` to `firebase-config.js` and fill in your project values.
4) Host these files on any static host (Netlify, Vercel, GitHub Pages, etc).

If Firebase config is missing, the app runs in local-only mode.
