Luminous Outpost
Five petrichor stops with room to breathe — #005354 grounds, #007f80 and #349a9b do the talking, #58a8a8 softens, #75c4c4 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.
