It was unreadable for me too initially. Quick guesstimate:
The page has a (JS-dependent) light-mode/dark-mode switch. It defaults to "light". Meanwhile a browser configured to default to dark theming will only partly apply the themed parts (the pages own function being stuck in light), resulting in an objectively unreadable black-on-dark-gray.
Even enabling JS, the button in the upper right corner still has to be clicked to make it readable.
