Nebula palette
Harbor Plaza
Five nebula stops with room to breathe — #0b409f grounds, #396cc9 and #5388e7 do the talking, #6b99eb softens, #8db6ff lifts. The analogous 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.
