Silvery Ridge
Five opera stops with room to breathe — #004b7e grounds, #0073be and #318fdc do the talking, #559fe1 softens, #71bbff 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.
