Video prompt: Ethereal 4K UHD video, 9s, 60fps, loopable, medium shot, vertical composition, a single girl wearing a plain-colored yukata, empty-handed, standing under a streetlight at a summer festival. Background: The streetlight diffuses a warm yellow glow, faint fireworks rise and burst in the distance, and the evening breeze gently blows the hem of her yukata (no extra characters/animals). Dynamic design: Character movement - slowly looks up at the fireworks, turns her head to face the camera, a faint smile touches her lips, and she blinks gently; Background movement - fireworks blooming, yukata hem fluttering. Lighting: Warm streetlight glow + cool fireworks light, an interplay of warm and cool tones, no text, no watermark. Style: Japanese summer festival, atmospheric, ethereal aesthetic. --ar 9:16 (Vertical, 1080x1920, YouTube Shorts Standard)
