Walnut Mill
Five opera stops with room to breathe — #004b7b grounds, #1674b5 and #3a90d3 do the talking, #5a9fd8 softens, #76bcf7 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.
