Build me a clean course site for this Computational Linear Algebra textbook.

It should present the notebooks in a simple, easy to browse way, with a homepage, a table of contents, and clear links to each lesson and the matching lecture videos. I want it to feel like a readable online class for people learning numerical linear algebra, not just a folder of notebooks.

Keep the style simple and academic, with enough spacing and headings that someone can scan the topics quickly. Make it easy to open the notebooks, and if you can, add short summaries for each lesson so people know what they are about before clicking in. I’d also like the pages to work well on GitHub and be easy to maintain as the course grows.

If you need to look up current docs or best practices for notebook based course sites, go ahead and use them.
