Frosted Boulevard
Five aurora stops with room to breathe — #005f9d grounds, #4089c8 and #5ca5e6 do the talking, #78b5ec softens, #a0d1ff lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
