Prompt: “Edit the uploaded portrait into a polished, approachable LinkedIn headshot while preserving the person’s exact identity, facial features, age, and natural skin texture. Use soft, flattering window light, a clean warm-gray background, and a head-and-shoulders crop with comfortable space above the head. Refine stray hairs and minor distractions subtly; avoid heavy retouching, artificial blur, altered facial structure, or added accessories.”
