Nebula palette
Raisin Orchard
Five nebula stops with room to breathe — #005678 grounds, #0081b1 and #349dce do the talking, #5babd6 softens, #78c8f4 lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
