Your Firebase config is already pasted in this file. If this screen doesn't disappear in a few seconds, check:
1. Are you opening this inside the Claude preview? That won't work — download the file and open it in Chrome/Edge/Firefox on your computer or phone.
2. Is your internet connected? The app loads Firebase from the web.
3. In Firebase console: is Authentication → Email/Password enabled, and have you added your admin user in the Users tab?
4. Is Firestore Database created, with the security rules from the comment at the top of this file published?
