It uses CSS nesting[1] (think SCSS) which requires Firefox 117 and Chrome 120 for full support[2]

Same, with Firefox on a Linux desktop, even after enabling JS.

Edit: apparently it uses Oklab/oklch() [1], which is supposet to work in Firefox since version 113, but does not seem to work in 115. Or possibly it also uses something else that breaks it.

If you can’t scroll down to see various swatch sets grouped by shade then you’re not seeing what you’re supposed to see. Works fine on FF for me but I don’t have Android.

Same on FF 50 on Linux.

I don't know how to call people who ignore backwards-compatibility. My sites work on IE6 if needed.

Same here, but on chromium PC.

Also using ff on Android.

No problems.

I also see just black text on white, on iOS / Mobile Safari.

I assumed it was a joke, like motherfuckingwebsite.com. But it seems that other people are seeing colors.
