Marble Estuary
Five industrial stops with room to breathe — #007084 grounds, #009db9 and #3cbad6 do the talking, #67c7e0 softens, #85e5fe 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 for large text.
