nwjs/blink ? reverse-engineered prompt

Build me a simple, clean website that explains this Blink repository and makes it easier to explore the LayoutTests content.

I want a homepage that says what this project is, a short overview of the engine mirror, and a clear section for browsing the test files or categories if that makes sense. Keep the design minimal and fast, with a layout that feels like a developer focused reference site, not a marketing page.

If you need to, look up current docs online so the wording is accurate. Make it easy to search or filter the visible test content, and add a few helpful empty state messages so it still feels polished if there is not much data yet. Use the existing files in the repo where possible, and keep the structure simple so it is easy to extend later.
