Chalky Garret
Five sumi stops with room to breathe — #831700 grounds, #bd371c and #dd553a do the talking, #e37058 softens, #ff8f76 lifts. The triadic bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
