Vaporwave palette

Peaty Bluff

Five vaporwave stops with room to breathe — #243cac grounds, #4869d7 and #6185f6 do the talking, #7698f8 softens, #9bb7ff lifts. The tetradic bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
