This part of the website's code was written with the assistance of Google's AI 'Gemini.' This mostly just means that things are less understood by me, and are probably buggy.
Specifically, the AI helped me setup the MathJax library to render math equations.

Currently I think there's a bug if you move between web pages on my site, but refreshing seems to fix it. Currently there are 20 cards. If you want to reorder the list again, just refresh the page.
