@Curator The (nice!) custom CW colours don't affect CWs in expanded posts. In addition to .status .content-warning, the selector should also include .detailed-status .content-warning. Or use just .content-warning to target both, like in the original CSS.

I wonder if perhaps reassigning the values of the colour variables would be better than these spot tweaks? It would certainly be more consistent. It's riskier since more stuff is affected, but similar values shouldn't cause too many issues.
