Birch Lighthouse
Five sumi stops with room to breathe — #711900 grounds, #ae310c and #cd4f2f do the talking, #d4684d softens, #f38468 lifts. The tetradic bones keep it coherent across wellness apps where the interface must feel calm, not clinical. The darkest and lightest stops clear AA as a text pair.
