This app uses Firebase Realtime Database for live sync across all players' devices. You need a free Firebase project — setup takes about 5 minutes.
Go to console.firebase.google.com, create a project (any name), then add a Realtime Database in test mode.
In Project Settings → Your apps → Add web app. Copy the firebaseConfig object values.
