Aurora palette
Sumac Caravan
Five aurora stops with room to breathe — #3c2692 grounds, #5f54bc and #786fda do the talking, #8783de softens, #a29ffd lifts. The split-complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
