Create a minimalistic mobile‑first React + Tailwind screen for a Telegram WebApp. Header: At the top of the page, display the text: Привет, username. Directly below it, add the subtitle: Это новый ASAP. Content: Below the subtitle, add a horizontal carousel of restaurants. Each restaurant card should include a restaurant name and a small logo or placeholder image. The carousel must be swipeable on mobile and scrollable horizontally on desktop. Below the carousel, place a large QR code for scanning at the restaurant cash desk. Design requirements: Minimalistic, clean layout. Mobile‑first, centered content, generous whitespace. Use a light background, simple typography, and subtle dividers. Avoid decorative elements and heavy shadows; focus on clarity and readability.
