Lantern Courtyard
Five opera stops with room to breathe — #005686 grounds, #0080c3 and #349ce1 do the talking, #5babe6 softens, #7fc8ff lifts. The split-complementary 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.
