Monochrome palette

Vernal Caravan

Five monochrome stops with room to breathe — #0b4b09 grounds, #3b7337 and #558e51 do the talking, #6b9b67 softens, #86b782 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.
