bklit/bklit-ui ? reverse-engineered prompt

Build me an open source UI library for React that focuses on charts and a few useful utility components, with a clean modern look and easy customization.

I want a site that shows a gallery of chart examples like area, bar, line, pie, radar, scatter, funnel, gauge, candlestick, choropleth, and live updating charts, with each one having a docs page and a little studio or playground where I can tweak it and see the result. The components should feel polished, reusable, and easy to drop into another app, with sensible defaults but lots of room to extend styles and behavior.

Please make it look like a real product site with a nice homepage, component docs, and example previews. If anything needs current setup details, look up the latest docs online and follow best practices.
