Raw Lighthouse
Five petrichor stops with room to breathe — #005f68 grounds, #008c98 and #37a8b4 do the talking, #5fb5c0 softens, #7cd2dd 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.
