Nebula palette
Pastoral Fjord
Five nebula stops with room to breathe — #004995 grounds, #3873bf and #538fdd do the talking, #6c9fe2 softens, #89bbff 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.
