Nebula palette
Violet Oasis
Five nebula stops with room to breathe — #004272 grounds, #316a9e and #4c85bb do the talking, #6494c2 softens, #7fb0e0 lifts. The triadic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
