Wisteria Lighthouse
Five monochrome stops with room to breathe — #00727f grounds, #00a0b1 and #3cbdce do the talking, #68cad9 softens, #86e8f7 lifts. The complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
