Nebula palette
Oat Depot
Five nebula stops with room to breathe — #004b4a grounds, #007775 and #319290 do the talking, #549f9d softens, #71bcb9 lifts. The tetradic 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.
