How GitHub Pages Database Works:
1. Single-Browser / Local Mode: Works automatically out-of-the-box using LocalStorage + IndexedDB.
2. Bake-In Mode: Any staff ID/password or task you add before clicking "Download GitHub index.html" is permanently embedded inside the downloaded file!
3. Live Multi-Device Cloud Mode: Paste any free Firebase Realtime Database URL (e.g. https://your-app-default-rtdb.firebaseio.com) below so all employees share live updates in real time!
