Aurora palette
Willow Oasis
Five aurora stops with room to breathe — #00585e grounds, #00848d and #35a0a9 do the talking, #5badb5 softens, #78cad1 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.
