I'm having trouble getting checks to run on /content/production/shifts/index.html likely because of the fancy graphs. This was addressed with a custom script where I can control how long (3 minutes) to wait for each page. If a page crashes or times out, the action will ultimately fail but all pages will still be tested. It seems like that page is always going to crash (GitHub Action Runners probably don't have enough RAM). For now, I'm going to leave it in so that way when I come back to address a11y violations I see what's going on. But likely the final solution will be to skip that page for the tests and monitor it manually with chrome extensions.
