Typography: Affinity vs Illustrator

The type.today site doesn't render any visible CSS for me (there's some inline CSS in the page source, but you can't see it on the page). It looks just like plain vanilla HTML set in Times New Roman (some headings in Arial), no images rendered. I tried Safari (also Technology Preview), Chrome, Opera and Vivaldi, all with the same result. Am I the only one that gets this?

It's rendering fine for me in Firefox, Safari, and Chrome.
