Flint Lighthouse
Five monochrome stops with room to breathe — #00687a grounds, #0095ae and #3ab1cb do the talking, #63bfd5 softens, #81dcf3 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.
