origin-brain/rust-by-practice ? reverse-engineered prompt

Build me a Rust learning site that feels like a hands on practice book, not a dry tutorial.

I want it to have lots of small Rust examples, exercises, and practice challenges, with solutions available for each one. The main goal is to help someone go from learning Rust basics to being able to solve real problems, so the exercises should range from easy to very hard. It should work as an online book that people can read in a browser, and I’d like English and Chinese versions.

Please make it simple to run locally too, so I can preview the book while editing. The pages should be clean and easy to follow, with code blocks that readers can edit and try themselves. If you need current docs for the book setup or Rust tooling, look them up online.
