Simmered Cove
Five sumi stops with room to breathe — #9d2100 grounds, #d74525 and #f76343 do the talking, #fd7f63 softens, #ffae9b lifts. The triadic bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
