itzap77/chathub-restructured ? reverse-engineered prompt

Build me a simple chat hub web app where people can open the site, see a clean chat screen, type messages, and get responses back in a smooth conversation view.

I want it to feel modern and easy to use, with a main chat area, a place to start a new chat, and a nice responsive layout that works on desktop and mobile. Keep the design clean and minimal, but make it look polished enough to use as a real product.

If there are any missing pieces, use sensible defaults and make the app run from the main Python entry point. Put the front end assets in the static folder and keep the app structure tidy so it is easy to extend later. If you need to check anything uncertain, look up current docs online and then wire it up in the simplest working way.
