Aurora palette
Lupine Pier
Five aurora stops with room to breathe — #005491 grounds, #367ebf and #539add do the talking, #6ea9e3 softens, #8cc6ff lifts. The split-complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
