Aurora palette
Luminous Estuary
Five aurora stops with room to breathe — #004a5b grounds, #00748e and #318faa do the talking, #549db4 softens, #70b9d1 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.
