ant-design/ant-design-mobile ? reverse-engineered prompt

Build me a mobile web UI component library for React that gives me the essential pieces I’d need to make app screens fast.

I want it to include common mobile friendly components like buttons, forms, lists, tabs, modals, inputs, pickers, and anything else that feels like a practical starting kit for a real app. It should look polished out of the box, work well on phones, and be easy to customize with themes and colors so different apps can make it their own.

Please make it feel lightweight and smooth, with good spacing, touch friendly interactions, and simple docs or examples so I can see how to use each component. Use TypeScript, keep the API clean, and make sure the whole thing is easy to install and use in a modern React project. If you need to check current best practices or docs while building it, go ahead and look them up online.
