Random thoughts:

- Seems great. Added to the backlog :)

- No colors in PDF illustrations. Is it a deliberate choice?

- > The first six chapters (and Appendix A) are essentially that book, but with the programming language changed to Python, some rewording, reformatting in Latex, and a few additions.

  Try [typst](https://typst.app/) as an alternative to Latex.

IANAL, but seems that what you need is Defensible Publication https://en.wikipedia.org/wiki/Defensive_publication to create reliable prior art

Is a container version in your roadmap?
