Lunar Outpost
Five nebula stops with room to breathe — #00538b grounds, #247cc2 and #4498e0 do the talking, #63a7e5 softens, #85c4ff 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.
