Luminous Boulevard
Five retro stops with room to breathe — #4e3b00 grounds, #7c6000 and #977a2a do the talking, #a38a4b softens, #bfa667 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.
