Flat vector illustration, clearly cartoon artwork, not a photograph. A cheerful autumn night Trunk or Treat scene: a row of three car trunks open and decorated with smiling jack-o\’-lanterns, string lights, autumn leaves, and bowls overflowing with wrapped candy and candy corn. Big friendly full moon and stars in a deep navy blue sky (#0B2A3C), warm tan and orange accents (#D9A86C), teal highlights (#134B63). No people, no faces, no text, no letters, no scary or spooky elements. Warm, joyful, family friendly, wide banner composition with open dark sky space on the left for a headline.
