Low Chignon with Soft Face Framing

Edit the uploaded reference portrait to preview a low chignon at the nape with a soft side part and two restrained face-framing strands; use a plausible amount of hair based on the reference. Treat the reference person as the identity anchor: preserve facial structure, apparent age, skin tone, expression, eyes, eyebrows, nose, lips, ears, body proportions, clothing and accessories. Keep the original pose, camera angle, crop, background and lighting. Change only the hair and pixels necessarily revealed or occluded by its new silhouette. Match strand detail, shadows, highlight direction and photographic grain to the source. Preserve natural hair color, including any gray strands. Reconstruct any newly exposed background or skin conservatively from nearby visible evidence. Anchor the bun at the nape with continuous gathered strands; avoid floating loops and keep ears and neck anatomically intact. If the requested style needs additional length or texture change, render it as a visual hairstyle simulation without altering the face or scalp anatomy. Do not add makeup, beauty smoothing, jewelry, text, watermarks, comparison panels or extra people. Return one realistic edited portrait.
