While I agree that the home page and navigation could be better structured, there is at least a Basic Concepts page linked in the sidebar. That page links to much more helpful description: https://tensegritywiki.com/index.php?title=Tensegrity
I use https://www.chezmoi.io/, which deals with that with templates and/or scripts. It's very flexible, so it can feel overkill, but I'm very fond of it.
I'm not the parent, but I did something similar. It's an editor for fractal flames where the UI is done in QML and rendering and generation is done in C++ and OpenGL. https://github.com/chaoskit/chaoskit
I liked that QML allowed me to iterate quickly on the UI. It was really quick to just compose a bunch of components together and have something working. I also enjoyed the integration with the C++ side. Overall I found QML pretty solid. If I'd build a desktop app again, I'd definitely consider it.
Over 10 years ago, it inspired me to play with strange attractors, which eventually ended with me writing https://github.com/chaoskit/chaoskit.
It was fun and I learned a lot, but it's definitely a deep rabbit hole. I've moved on since then.
