sandypbk23-ui/Orvix_Chat ? reverse-engineered prompt

Build me a modern chat app where people can sign up, log in securely, and start messaging each other right away.

I want it to feel fast and clean, work well on desktop and mobile, and update messages in real time without needing to refresh. Make the main experience simple, with a good chat layout, a clear list of conversations or users, and a smooth messaging screen. Please include the full app setup, both the server and the front end, and make sure the whole thing is wired together so it actually runs.

If you need to check current docs or best practices while building it, go ahead and look them up. Focus on making it polished, easy to use, and ready for a real app demo.
