Vaporwave palette

Halcyon Dune

Five vaporwave stops with room to breathe — #8733b5 grounds, #b164e0 and #ce81ff do the talking, #d79bff softens, #e7c6ff lifts. The complementary bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
