Reusable English prompt
Use the uploaded reference image as the primary identity source. The generated runner must match the same person exactly, preserving precise facial structure, skull shape, jawline, cheekbones, eye shape, nose shape, lip shape, eyebrow thickness, hairline, hairstyle, skin tone, facial hair pattern, and overall anatomical proportions. Maintain true identity fidelity and likeness. Do not beautify, stylize, or alter facial features. Preserve natural asymmetry, skin texture, and facial geometry. The person must remain clearly recognizable. Create a hyper-realistic sports photograph of the subject running at the front of a marathon or road race on a wide metropolitan city street. Portrait orientation, 4:5 aspect ratio, ultra-detailed 8K realism, professional athletic photography.
