Nebula palette
Flint Mesa
Five nebula stops with room to breathe — #98000a grounds, #cc3b34 and #ec5a4f do the talking, #f27569 softens, #ff9f93 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.
