Mercurial Courtyard
Five monochrome stops with room to breathe — #00474f grounds, #00727e and #308d99 do the talking, #529aa5 softens, #6fb7c1 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 as a text pair.
