"Using the reference image, keep the battery pack exactly as it appears — same shape, color, casing design, terminals, handle, and any visible labels or markings — do not alter its design or details. Scene: A realistic indoor photograph in a practical repair setting — a home garage or small workshop space (soft natural daylight mixed with warm overhead lighting). A red four-wheeled mobility scooter (red frame, black seat, front basket, handlebar controls) is parked on the floor, tilted slightly or propped on a low stand, with its battery compartment open beneath the seat. A friendly mobility service technician — short dark hair, light stubble beard, wearing a navy blue polo shirt with a mobility company logo embroidered on the left chest, dark navy work trousers, and tan work boots — is crouched or kneeling beside the scooter, focused on the open compartment, holding a small tool (screwdriver or pliers) in one hand. Beside him on the floor, placed carefully on a cloth or mat, sits the reference battery pack — clearly the one just removed from the scooter, with a few small tools (screwdriver set, multimeter) laid out neatly nearby. His expression is calm, methodical, and professional, sleeves slightly rolled up, fully absorbed in diagnosing the issue. Background: a practical workspace — shelving with spare parts and tools, a workbench along one wall, concrete or tiled flooring, soft natural light from a window or open door. Homey yet functional atmosphere, realistic photographic lighting. Camera angle: eye-level, medium shot capturing the technician, the scooter, and the reference battery on the floor clearly within frame, shallow depth of field with the background softly blurred. Photorealistic style, natural color palette, documentary/lifestyle photography aesthetic conveying careful diagnostic work."
