Vertical full-body activewear campaign photograph, camera positioned far enough away to show one adult male model completely from the top of his head through both shoes, with generous clear space above his hair and below his soles, centered beside a contemporary running track. He wears a completely plain unbranded slate-gray performance jacket, matching joggers, and plain running shoes. Natural standing pose, both hands fully visible with five anatomically correct fingers, accurate body proportions, crisp early-morning light, clean stadium background. Every garment must have smooth uninterrupted fabric with absolutely no logo, emblem, icon, lettering, graphic, badge, patch, symbol, or decorative mark. No text and no watermark. Do not crop the head, legs, ankles, or shoes.
