cssnano has had some complicated ownership turnover[0], I'm glad to see someone took the mantle again though.
I do find that CSSO[1] with structural optimizations can be more effective still, perhaps that will be less true overtime though.
I think once lightning CSS is more stable (in particular, some bugs are addressed around ordering) it will be the clear winner in this space though.

Project mention: Generating Voronoi Diagrams Using Fortune's Algorithm (With Odin) | news.ycombinator.com | 2025-02-08
I made an implementation in clojurescript that animates the algorithm as it goes a while back: https://voronoi.ajwerner.net/#/app-diagrams
It’s a very beautiful algorithm.
However, after that project I sort of came to dislike Fortune’s algorithm because it isn’t numerically stable with floating point numbers. If you have points that are colinear, or nearly colinear in fp, things can break. The delaunator is better in this regard iirc: https://github.com/mapbox/delaunator
