easychen/howto-make-more-money — reverse-engineered prompt

I want a simple Chinese online book site for this content, based on the existing chapter markdown files and images. It should read like a small book called 程序员如何优雅的挣零花钱, with a nice cover, chapter navigation, table of contents, and clean reading pages that work well on desktop and mobile.

Please keep everything in Chinese and make it clear this book is mainly for readers in China, not really for foreigners. Include the existing visuals like the cover, mind map, QR code, and class image where they make sense. I also want a readable homepage with the book intro, update notes, links to related resources, and links for free online reading.

If possible, also make it easy to export or publish as a static site and ebook style output from the markdown source. Keep the style lightweight and elegant, more like a polished little handbook than a blog. You can look up current docs online if needed.
