walkinglabs/learn-harness-engineering ? reverse-engineered prompt

Build me a beginner friendly course website for “Learn Harness Engineering” that teaches people how to make AI coding agents more reliable, not just by prompting better, but by setting up the right project environment around them.

It should feel like an official project based tutorial with a clear homepage, visual course preview, learning path, syllabus, resource library, and a capstone project section. The content should explain ideas like instructions, state tracking, verification, scope control, and session lifecycle in plain English, with diagrams or simple visual blocks where helpful.

Please include multilingual entry points for English, Chinese, Russian, Vietnamese, and Korean, since the course links to those versions. Also include a way to build downloadable PDF coursebooks for at least English and Chinese, with generated files going into an artifacts folder.

Make it polished and practical, with templates or references for things like AGENTS.md, feature lists, init scripts, verification workflows, and progress logs. Look up current docs online if you need to.
