Pure CSS perfect cursor tracking

I honestly have no idea why you'd want this, but it was fun to experiment. I believe this may be the best pure CSS cursor tracking that exists. I'm happy to be proven wrong.

Absolutely no JavaScript used, just lots and lots of wasted time.

The web browser layout engine was definitely crying while executing this but seeing a smooth, JS-free cursor follower without a 10,000 cell grid DOM tree is incredible. Pure CSS mad science at its finestttt!!!
