照片写实图像增强

Ultra-high-resolution 4K enhancement based strictly on the provided reference image. Absolute fidelity to original facial anatomy, proportions, and identity. Preserve expression, gaze, pose, camera angle, framing, and perspective with zero deviation. Clothing, texture, environment and colors must stay the same. Improve sharpness, fine texture, reduce noise, add tiny realistic surface details. Do NOT change artistic style, do NOT alter composition.
