@81192x cinematic underwater sequence from a disaster film: A massive tsunami hits a coastal metropolis, a ( @81192x ) is dragged into churning, silt-filled seawater; close-up of their panicked face, bubbles streaming upward, floating debris (wood, metal, glass) crashing past, sunbeams filtering through murk, handheld camera with subtle shake, realistic water dynamics, dramatic color grading (desaturated blues, high contrast), ambient sound of rushing water and distant screams.
