Generate a 3:4 vertical "city film title poster". Do not use a reference image, do not generate a real celebrity face, and do not make it a glamour photo. The image should look like a real theatrical-release movie poster, not an ordinary AI landscape. Poster theme: A city youth film that does not exist. Title: 《fill in the title here》 Scene setup: Around the title, generate an urban everyday scene with a sense of story. Characters may appear, but no large face close-ups; they exist only as the emotional subject. The focus is the scene, light and shadow, atmosphere, and the title typography. Composition: 3:4 vertical poster composition. Place the figure at one-third of the frame or small in the distance. The image must keep a large area of negative space for the Chinese title and subtitle. Overall it should feel like real movie promo material. Typography: The main title uses a large Chinese movie-title typeface, placed at the bottom or in the left negative space. The subtitle uses a small Chinese typeface, above or below the main title. You may add the year «2026», release info, and minimal showtime text, but no large blocks of text. The text must be clear, restrained, and hierarchical, with no garbled characters and no wrong English letters. Visual style: city youth film, arthouse movie poster, low-saturation film color, real-life scene, natural light, slight film grain, restrained negative space, clean layout, movie-promo poster texture. Avoid: no cyberpunk, no anime, no influencer glamour shots, no cheap filters, no complex effects, no watermark, no logo, no wrong text, no extra fingers.
