Aurora palette
Pewter Manor
Five aurora stops with room to breathe — #006d91 grounds, #0099ca and #3bb6e8 do the talking, #66c4ef softens, #9ddfff 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.
