Gloaming Bluff
Five monochrome stops with room to breathe — #005f8e grounds, #008acb and #37a6e9 do the talking, #5fb5ef softens, #90d1ff lifts. The analogous bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
