The 3.57MB background PNG is hilarious [0]

I got it down to 1.03MB by just switching the png to palette encoding mode.

They could have saved themselves 3MB by converting it to AVIF.

Ha! I normally wouldn’t find it quite so hilarious, but it’s a stylistically pixelated image. There’s just too much irony packed in there to not chuckle.
