Nebula palette
Spruce Prairie
Five nebula stops with room to breathe — #005b78 grounds, #0086af and #36a2cc do the talking, #5db0d4 softens, #7acdf2 lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
