Zephyr Lighthouse
Five monochrome stops with room to breathe — #007a42 grounds, #00aa5f and #3dc77a do the talking, #69d491 softens, #87f2ad 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.
