Not really. Any solar system proves a kind of stability. And so does the famous KAM theorem.
It states that a periodic solution is indeed quasi-stable under small pertubations. And yes, small sometimes is extremely small. But still stable. Imagine a sharp point with a tiny dent.
We used GitHub/Azure markdown plus Mermaid plus MathJax for financial model documentation.
Beyond a certain complexity this really hurts.
Now we use typst, both playground (which does not call home, so no document exfiltration) or the compiler. The compiler is super easy to install, as we already have the Rust build chain installed.
Compared to Tex, the 40 odd years newer design of typst makes all the difference.
