Nebula palette
Coral Cove
Five nebula stops with room to breathe — #00635f grounds, #00908b and #38aca7 do the talking, #60b9b4 softens, #7dd6d1 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.
