Aurora palette
Sunlit Beacon
Five aurora stops with room to breathe — #474e9f grounds, #6e78c9 and #8894e7 do the talking, #9aa5ed softens, #b9c3ff lifts. The triadic bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
