Handheld Street Shot After a Sudden Loud Crash

Single continuous observational handheld shot at shoulder height following the woman from the starting frame as she walks forward through the crowded city street in warm late-afternoon light. Subtle natural handheld instability and visible film grain for the first several seconds. Then a sudden loud crash and bang erupts off-camera from behind her to the left. She reacts sharply with surprise and fear, eyes widening and body tensing as she turns slightly. The surrounding crowd flinches, ducks, turns, and begins to scatter, with people rushing across the foreground. The camera operator is startled too: the frame jolts hard, becomes markedly shakier, tilts slightly off-kilter, briefly struggles with motion blur as bodies cross the lens, then tries to recompose on her while staying reactive and human rather than random. No cuts, no zooms, no slow motion.
She remains roughly the same size in frame throughout.
Preserve the exact woman, dark brown coat, deep red scarf, warm muted cinematic texture, and film grain from the first frame. Audio: soft street ambience and footsteps, then a sharp loud metallic crash or bang from the left, followed by gasps, startled shouts, and rapid scattering footsteps.
