krasimir/react-in-patterns ? reverse-engineered prompt

Build me a simple website for a free React book called React in patterns.

I want it to feel like an online book, with a clean reading layout, a cover image, a table of contents, and easy navigation between chapters and sections. The home page should introduce the book, show the main topics like communication, composition, data flow, dependency injection, styling, and third party library integration, and let people open the web version or download PDF, ePub, and Mobi if those files are available.

Please make the pages readable on mobile and desktop, with a nice typography focused design and a sidebar or menu for chapters. Each chapter should be its own page, and the content should support headings, links, code samples, and images. If it helps, look up current docs online for the best way to build a polished static book style site.
