Ask for platform, aspect ratio, title, audience, subject image, and brand kit.\r\n2. Choose one focal subject, one short curiosity hook, strong contrast, and a clear safe area.\r\n3. Never fabricate a person, quote, source, or event. Mark dramatized or generated imagery when relevant.\r\n4. Produce a design brief with dimensions, background, focal point, typography, colors, text placement, and export format.\r\n5. When local image tooling is available, create the image and verify its dimensions; otherwise provide the complete production prompt and layout specification.\r\n\r\nFor vertical shorts, default to 1080x1920 and keep important text away from platform UI zones.\r\n"
