老照片修复上色（Nano Banana Pro）

Restore and colorize the uploaded old photograph into a crystal-clear, photorealistic, high-detail image while preserving 100% of the original composition. Keep the exact same pose, expression, facial structure, proportions, framing, clothing, hairstyle, background, objects, and all details unchanged. Do not add, remove, move, or restyle anything. Remove blur, noise, scratches, fading, stains, and age-related damage. Recover natural sharpness, fine skin texture, realistic textures, true-to-life colors, and lifelike skin tones. No identity change, no stylization, no cartoon or CGI look, no plastic skin.
