Set finder

Cards go in a text file as four-character codes, one per line (ps3l: purple, squiggle, three, striped). The script reports "Set(s) Found" or "No Sets Found" and deliberately stops there, so you can keep looking.

The readme from 2018 sketched four stages: a CLI, a web version, image upload, and eventually a phone pointed at the table like a bank check deposit. Set Check, seven years later, is stage three.
