Apologies for the giant PR, but I wanted to add PNG versions in all sizes for all variations. The 16x16 PNG variants didn’t turn out so well, but everything else looks great—at least to my backend developer eyes! 😆 I used ImageMagick and Inkscape for the conversion. If you know a better incantation, go for it!
