Aurora palette
Fiery Foundry
Five aurora stops with room to breathe — #4432a8 grounds, #6860d3 and #817cf2 do the talking, #9190f4 softens, #afb0ff lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
