Eeshan-Vaghjiani/Chat-REACT ? reverse-engineered prompt

Build me a modern real time chat app called SuperChat with a clean blue look and a smooth, friendly feel. I want people to sign in with Google, see their profile photo and name, and start chatting right away. Messages should show up instantly for everyone, with a typing indicator while someone is writing, and it should load a small message history when the chat opens so it does not feel empty. Make it work nicely on both desktop and mobile, with a simple layout that feels polished and easy to use. Please use React and Firebase for authentication and storing messages, and make sure the app is set up so it can be deployed on GitHub Pages. Add sensible loading states and basic error handling too. If you need to check the latest Firebase or deployment docs while building it, go ahead and look them up online.
