Opera palette
Timbered Plaza
Five opera stops with room to breathe — #9b3700 grounds, #d75619 and #f7733c do the talking, #fd8c60 softens, #ffb99e lifts. The monochromatic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
