Nebula palette
Lunar Pavilion
Five nebula stops with room to breathe — #006e96 grounds, #009ad1 and #3bb7ef do the talking, #66c5f6 softens, #a5dfff 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.
