gaurangagar/intervux ? reverse-engineered prompt

Build me a polished web app for practicing interviews, with a clean landing page and a simple flow where someone can start a session, answer questions, and see the conversation update in real time.

I want it to feel modern and easy to use, with a nice dashboard area for past sessions or notes, and a backend that saves the important data so users can come back later. If it helps, use the existing setup for the main app, database storage, and live updates, and look up current docs online if you need to.

Please make the experience smooth on desktop and mobile, keep the UI simple and friendly, and wire everything together so it actually works end to end.
