背景にサンタが登場

Add a realistic, quietly Santa figure in the background of the uploaded photo, as if he is naturally and almost accidentally caught on camera. Keep the subject completely unchanged. Place Santa partially obscured - for example, a glimpse of him stepping through a doorway, passing a hallway, or silhouetted near a window. His presence should feel understated and believable, not exaggerated. Santa should appear as a real man in a classic red winter coat with white trim, but slightly muted and natural - soft fabric, not overly bright. The lighting on him must match the room, with gentle shadowing so he blends into the environment. His posture should be cautious: mid-step, leaning slightly forward, or turning as if making sure no one sees him. He should carry a bag loosely over one shoulder, only partially visible. The overall effect should feel like a quiet, cinematic holiday moment - as if the camera unintentionally captured Santa slipping into the house. No magical sparkles, no cartoon exaggeration, just a believable, subtle presence integrated seamlessly into th background.
