修复并上色受损老照片

Using REFERENCE_0, restore the old damaged family photo into a clean, high-resolution modern scan. Remove the heavy scratches, stains, fading, tears, and surface damage while preserving the original composition, pose, framing, and background curtain. Reconstruct realistic natural skin tones, sharpen details, and colorize the image with believable warm indoor tones. Keep the woman holding the baby in the same position, restore the black sleeveless dress, the baby's light outfit, the reddish-brown hair, and the subtle necklace. Maintain the same portrait crop and photographic realism, as if the original print was professionally repaired and remastered in 4K.
