Japanese Negative Film Rooftop Portrait

Create a {argument name="style" default="Japanese negative film style"} rooftop summer portrait with soft natural sunlight, slightly overexposed highlights, low contrast, muted faded colors, and subtle film grain. The subject is {argument name="posture" default="standing or sitting"} near the edge of a rooftop, relaxed in posture, with a light breeze moving their hair and clothing. They look toward the camera with a calm, distant gaze, not overly posed. Keep the sky open with plenty of empty space, very few background elements, an imperfect candid composition, and a quiet isolated mood. The image should feel nostalgic, reflective, realistic, and memory-like. Use a 2:3 aspect ratio.
