Linen palette
Halcyon Delta
Five linen stops with room to breathe — #71280e grounds, #9b523a and #b86c54 do the talking, #c2806a softens, #df9b85 lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
