Glassy Lighthouse
Five sumi stops with room to breathe — #a14600 grounds, #df6400 and #ff8134 do the talking, #ff9c68 softens, #ffc8ac 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 for large text.
