Retro palette
Maple Oasis
Five retro stops with room to breathe — #7d0021 grounds, #b03343 and #cf505c do the talking, #d66a70 softens, #f6868b lifts. The monochromatic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
