Build me an ultra realistic chat game where the whole experience feels like you are talking to a smart character in real time. I want it to be a polished Next.js app with a clean modern UI, styled with Tailwind, and it should use Giga Chat for the AI responses.

The main screen should look and feel like a believable chat app, with message bubbles, typing state, smooth scrolling, and a strong mobile friendly layout. Make it feel immersive and game like, not like a plain demo. I also want the app to be ready for deployment on Vercel, and if it makes sense, include basic analytics with Yandex Metrika.

Please set it up so I can run it locally with a simple install and dev command, and make the code organized and easy to extend later. If you need to check the current docs for anything, look them up online.
