Comment (by ryelle):

 Thanks! I've updated the checkmark & radio to `#3582c4` which has a 4.08
 contrast against white. I also updated yellow-50 in the palette to
 `996800`, which ''just'' clears the 4.5 contrast against the alternate
 background.

 I happened to notice the UI helper classes would lack contrast, so I
 bumped up the blue there, too.
