Illustration, Expressionism, jewel tones, moonlight, floating particles: A stylised drawn scene of young silhouettes planting glowing emerald seedlings that rise into a sapphire city of light, their hands and gentle helper-robots tending luminous roots. Paper boats and kites sail toward a bright horizon under cool lunar glow. Deep amethyst sky, jagged strokes convey wonder and growth, no real people, no text.
