Aurora palette
Waxed Cabin
Five aurora stops with room to breathe — #2e3479 grounds, #525da2 and #6b78bf do the talking, #7c88c6 softens, #97a4e4 lifts. The complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
