Nebula palette
Mineral Reef
Five nebula stops with room to breathe — #004183 grounds, #1f69bd and #3d85db do the talking, #5a95df softens, #75b2fe lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
