Nebula palette
Rustic Deck
Five nebula stops with room to breathe — #00485d grounds, #007291 and #308dad do the talking, #539bb6 softens, #6fb7d4 lifts. The triadic bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
