Powdery Boulevard
Five nebula stops with room to breathe — #004d44 grounds, #00796c and #329486 do the talking, #55a195 softens, #71beb1 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.
