Nightfall Lighthouse
Five jewel stops with room to breathe — #2241b4 grounds, #486fdf and #618bfe do the talking, #789eff softens, #a2beff lifts. The triadic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
