Rocky Junction
Five opera stops with room to breathe — #004e72 grounds, #2477a5 and #4392c2 do the talking, #61a1ca softens, #7dbde8 lifts. The complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
