国内灾难：膨胀的肥皂泡沫蔓延整个社区

First-person POV camera looking down at two hands in latex kitchen gloves pressing a soap dispenser at a bathroom sink, a completely ordinary domestic morning. The soap emerges. At the 2-second mark the foam expands beyond the palm still expanding, pushing both hands outward, filling the sink basin in four seconds, overflowing the counter in six. Camera pulls back as the foam volume doubles every two seconds: doorframe, hallway, staircase, the foam moving with the same even pressure in all directions simultaneously, furniture disappearing beneath the surface. The camera is riding the foam's leading edge, always just ahead of submersion. Outside window visible at the midpoint: the foam is exiting the house from every opening. Aerial pull-back reveals the entire neighborhood block going white. Warm bathroom light transitioning to overcast outdoor grey as scale expands. Foam-expansion velocity ramp, scale-shift reveal, deadpan domestic catastrophe, photorealistic soap physics, 4K.
