Quiet Reef
Five retro stops with room to breathe — #003688 grounds, #285fb9 and #427bd7 do the talking, #5b8bdb softens, #76a8f9 lifts. The monochromatic 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.
