    - Preserve upstream wording, headings, section order, assignments, and overall chapter flow as closely as practical
    - Do not summarize, reinterpret, or "website-optimize" the course into a different learning experience
    - Only adapt what the website requires: Astro frontmatter, route-safe internal links, GitHub repo links, local asset paths, and minor HTML/CSS hooks needed for presentation
+    - Convert repo-root relative links that are invalid on the published website (for example `../.github/agents/`, `./.github/...`, or `.github/...`) into absolute links to `https://github.com/github/copilot-cli-for-beginners` (use `/tree/main/...` for directories and `/blob/main/...` for files)
