Transform the uploaded photo into a professional, hyper-realistic headshot. Keep the person's face, identity, facial structure, natural features, age, expression, and overall appearance accurate to the uploaded image. Style the final image like a high-end personal brand / LinkedIn / founder headshot: tight portrait framing from upper chest to just above the head, subject centered and facing the camera, natural relaxed expression with a slight confident smile, clean polished skin while keeping realistic texture, pores, and natural imperfections, sharp focus on the eyes, soft flattering lighting from the front-left, subtle catchlights, realistic depth of field, smooth blurred background with warm indoor tones, 85mm portrait lens look at wide aperture, natural color grading with warm highlights and soft contrast, clean modern premium editorial feel. Clothing: simple, modern, professional dark minimal top such as a black sweater. Background: softly blurred modern office, studio, or upscale interior in neutral dark and warm tones, no logos or text. Preserve the person's real identity and facial proportions; do not make it look AI-generated, no plastic skin, no changes to ethnicity, gender, age, facial structure, or eye shape; output should look like a real professional headshot.
