Petrichor palette

Silvery Caravan

Five petrichor stops with room to breathe — #644a00 grounds, #956f00 and #b18a2f do the talking, #bc9b54 softens, #d9b770 lifts. The split-complementary bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
