Nebula palette
Oat Meadow
Five nebula stops with room to breathe — #4a1197 grounds, #6e48c1 and #8764df do the talking, #947ae3 softens, #b097ff lifts. The analogous bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
