It's a high school math textbook, and it's available at https://woodlandsmathematics.ml (but locked under a password). I'm also remaking the architecture for the other, upcoming textbooks.
It would be nice if you can keep live at least a free "paswordless" chapter, and add a link in your CV. But you must talk to the teacher(s) to be sure it's ok.
What does this mean:
> Decreased point‑of‑interactivity times from 7 seconds to 1 second
Any insight about the problem or the solution?
