Snailclimb/JavaGuide ? reverse-engineered prompt

Build me a clean, easy to read knowledge site for Java interview prep, mostly in Chinese, with English and Japanese versions too.

I want it to feel like a study guide for backend developers, with clear sections for Java basics, collections, concurrency, JVM, operating systems, databases, distributed systems, high concurrency, system design, and AI app development. It should have a nice homepage, simple navigation, a strong search experience, and article pages that are comfortable to read on mobile and desktop.

Please make it look polished and modern, but not flashy, since the main goal is learning. Add a special interview crash course area, a roadmap for preparing step by step, and obvious links to the main reading version and the shorter quick review version. If you need to check current docs or best practices for the site framework, look them up online.
