Not a huge surprise that paste-dark-mode-color-filtered.html is failing, as the heuristic is changing. Need to see if the new results are acceptable.

Typically we try not to name functions that compute values with verbs. So we would name it shouldUseConvexGradient.

Maybe do the behavior change, the switch to luminance, first in a patch that doesn’t also refactor or remove.

Just going to do the isDark change in this one. Leave the lightness() for separate change.
