Nebula palette
Kelp Foundry
Five nebula stops with room to breathe — #005b56 grounds, #008881 and #36a49c do the talking, #5cb1aa softens, #79cec6 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.
