Crackling Crossing
Five monochrome stops with room to breathe — #004769 grounds, #0070a3 and #308bc0 do the talking, #539ac7 softens, #6fb6e5 lifts. The complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
