sungeer/ai-agent-book ? reverse-engineered prompt

Build me a clean open source website for this AI agent book, with the full Chinese text and the translated versions in other languages.

I want people to be able to read the 10 chapters online, switch languages easily, fold and unfold chapter sections, and search the full text. It should also let visitors download the latest PDF and EPUB versions, and show the chapter linked experiments so someone can jump from the book into the matching code examples.

Please make it feel polished and readable on desktop and mobile, and keep it easy to update whenever the main branch changes. If you need current docs or a better way to handle the book build and publishing flow, look it up online and use the simplest reliable approach.
