attiquerehman1/chatbot ? reverse-engineered prompt

Build me a simple chatbot app that opens in the browser and lets a user type messages and see replies in a clean chat window.

I want it to feel polished and easy to use, with a conversation area, a message box, and a send button, plus basic styling so it looks like a real modern chat app. If it needs any extra setup to work, please wire that up too and make sure it runs from the solution cleanly.

If something is unclear, keep it simple and make reasonable choices, and look up current docs online if you need to.
