The Tailwind slate greys were cold. Each one is now r=g=b at its own OKLab lightness, so every contrast stays where it was: the theme's chrome, the path chips, the map's roads, labels and buildings, the heat tail, and the emulator window. test_neutral_greys fails any #rrggbb literal that reads as a grey and has a tint.
