  "prompt": "Realistic gym mirror selfie of [a young athletic man with slightly messy blond hair] sitting on a workout bench inside a modern fitness center. He has a focused, neutral expression while looking down at his smartphone, holding it with both hands. Attire includes [a black oversized hoodie], [short athletic shorts], and wireless earbuds. Relaxed post-workout seated posture with legs spread naturally. The gym environment behind him shows weight machines, barbells, and weight plates reflected in the large mirror under bright overhead commercial gym lighting."
