Using the uploaded selfie as exact facial reference, generate a photorealistic professional headshot suitable for LinkedIn. Pose at 3/4 angle with a gentle, confident smile, eyes to camera. Wardrobe: navy blazer over white shirt, no patterns. Background: neutral light gray studio gradient. Lighting: large softbox key at 45° with soft fill, clean catchlights, no harsh shadows. Lens look: 85mm portrait compression, shallow depth with eyes tack-sharp. Color: natural skin tones, minimal retouching, realistic pores and hair detail. Crop: head-and-shoulders, 1:1 or 4:5. Preserve identity precisely; avoid plastic smoothing and face reshaping.
