Nebula palette
Quilted Orchard
Five nebula stops with room to breathe — #00746f grounds, #02a29c and #3dbfb8 do the talking, #68ccc6 softens, #86e9e3 lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
