Nebula palette

Indigo Lighthouse

Five nebula stops with room to breathe — #006d94 grounds, #3e98c1 and #5cb4df do the talking, #7bc3e7 softens, #a1dfff lifts. The split-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.
