Marble Cabin
Five nautical stops with room to breathe — #004e5f grounds, #007991 and #3294ad do the talking, #56a2b7 softens, #73bfd4 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.
