I cannot answer to @jomaxro over there but there is a little stylesheet issue when I run this in my Android 9 Kiwi Browser 101.0.4951.40:
The text appears on top over the coloured discs instead of beneath.
So it’s not as legible as it is intended to be in the design screen captures.
Same occurs even when I disable all my extensions, Stylus and Violentmonkey.
