telegram-mini-apps-dev/TelegramUI ? reverse-engineered prompt

Build me a React component library for Telegram Mini Apps that feels like Telegram itself. I want a clean set of ready to use UI pieces such as a root app wrapper, placeholders, buttons, and other common app building blocks, all styled for Telegram’s look and feel and working nicely in both light and dark color schemes.

Make it responsive, friendly for mobile, and usable in modern browsers as well as Telegram clients and server side rendering. Include a simple way to import the styles and use the components in a small demo app, with a Storybook style playground so I can see and test the components easily.

Keep it polished, consistent with Telegram’s interface, and easy to customize for different mini app ideas. If you need current docs or design references, look them up online.
