Opal Atelier
Five retro stops with room to breathe — #8a3e2f grounds, #b56858 and #d38372 do the talking, #dc9788 softens, #fbb3a3 lifts. The split-complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
