Aurora palette
Prairie Fjord
Five aurora stops with room to breathe — #004d63 grounds, #007897 and #3293b3 do the talking, #56a1bd softens, #72beda lifts. The triadic bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
