Halcyon Shrine
Five blue hour stops with room to breathe — #004b8f grounds, #2374c8 and #4290e6 do the talking, #60a0ea softens, #85bdff 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.
