Nebula palette
Lingering Cabin
Five nebula stops with room to breathe — #004462 grounds, #006d9a and #2f88b7 do the talking, #5197be softens, #6db3dc lifts. The split-complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
