Monochrome palette
Lunar Fjord
Five monochrome stops with room to breathe — #004b1f grounds, #007836 and #309350 do the talking, #52a066 softens, #6ebd81 lifts. The tetradic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
