Sunset Canyon
Five aurora stops with room to breathe — #0b4b8c grounds, #3d74b6 and #588fd4 do the talking, #709fda softens, #8bbcf8 lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
