Daylight palette

Parchment Dune

Five daylight stops with room to breathe — #006b77 grounds, #0098a9 and #3ab4c6 do the talking, #64c2d1 softens, #82dfee 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 for large text.
