Bonus: Can this be a pure CSS library?

I thought CSS was generated by JS these days? Apparently it was too difficult to remain its own thing.

Yes, most of it can. I remade this effect using CSS animations, as an exercise:

However, a limitation of not using JavaScript is that I can’t randomize the changed properties: the page changes in the same way after every reload.

I think you could do it with keyframes, though the "randomness" would have to be hard-coded (the same every time)
