LAYOUT / ROWS / COLUMNS were 10px text-gray-400: about 2.5:1 on white,
where WCAG wants 4.5:1 at that size. Their own class rather than a darker
grey utility, because in dark mode text-gray-400 and text-gray-500 both
resolve to --text-muted (#61656e, nearer 2:1 on the panel) -- swapping the
utility would have fixed light mode and left dark exactly as it was.
