Steely Bluff
Five storybook stops with room to breathe — #004d5a grounds, #00788b and #3293a7 do the talking, #55a1b1 softens, #72bdce 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.
