Build me a Telegram web app that feels like the modern Web K version, fast and clean, with the usual chat experience people expect.

I want a single page web client where someone can log in, see their chats, open conversations, send and receive messages, and handle common things like emoji, stickers, images, files, and voice messages. It should work well as a progressive web app, look good on desktop and mobile, and feel snappy even with lots of chats and media. Keep the interface polished and familiar, with a strong focus on usability and performance.

Use the current Telegram web app behavior as the reference, and if you need to check anything unclear, look up the latest docs online. I’d also like it to be easy to run locally for development and to build into a production ready version.
