Rule Pool

 This was originally shared on 6/3/24. It's one of my favorite metapuzzles I've ever made, but I suspect I didn't post it here before because I thought I'd repurpose it for a later project, which I chose not to do.

Here are two shading puzzles with similar clue layouts but completely different rulesets. As for the rules... clears throat and sifts through notecards

Whoops! I... uh... accidentally dropped them. Which rules went to which puzzle again?
