Oyster Atelier
Five nebula stops with room to breathe — #892200 grounds, #c73d13 and #e75b36 do the talking, #ed7657 softens, #ff9c81 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.
