there's 22 cards (I think) in final build... if you poke through the source code by inspecting the game element, you can find a script tag with the RANDOMGEN id, and in the dict.card object you can see them all. Some of them are generative, so like The Moon card actually calls out to the {moongen] function and you can see how it's put together. for cards like that there's no "stable" description cause it can switch between a bunch of alternate moon states. a few other cards are like that--like The Armory pulls randomly from the [weapon] corpus three times for its description. but yeah that's where at least the skeleton of the different cards is set
I could post that code here but it might get a bit messy since it doesn't look like itchio has a way of posting code blocks...
