Nebula palette
Violet Archive
Five nebula stops with room to breathe — #00537a grounds, #007db5 and #3399d2 do the talking, #59a8d9 softens, #76c4f7 lifts. The complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
