Hi! 👋

I would like to work on this issue. I've already analyzed the codebase and identified all the missing dependencies.

Here's my plan:

1. Update requirements.txt with all Sphinx extensions used in conf.py:

   • sphinx-togglebutton
   • sphinx-copybutton
   • sphinx-design
   • sphinx-book-theme
   • sphinx-jupyterbook-latex
   • sphinx-multitoc-numbering

2. Update environment.yml to stay in sync with requirements.txt

3. Add version pinning for jupyter-book>=1.0.0 to ensure compatibility

4. Test locally by building the book with sphinx-build

I've already updated environment.yml locally and tested it. I'll submit a PR shortly.

Could you please assign this issue to me? This is my first open source contribution and I'm excited to help!
