Vaporwave palette

Brumal Lighthouse

Five vaporwave stops with room to breathe — #3e5098 grounds, #657ac2 and #7f96e0 do the talking, #92a6e6 softens, #b0c3ff lifts. The monochromatic bones keep it coherent across dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
