AI Video Prompt: Truck Brick Load Collapse

A photorealistic, handheld vertical video (9:16) shot at a bright, sunny construction site. A white conventional semi-truck with a long flatbed trailer is carrying a massive, towering stack of red bricks, stacked much higher than the truck cab. The background features an unfinished concrete building and a yellow crane against a blue sky. The truck drives forward on a dry dirt lot. As it moves, the rear section of the brick load suddenly shifts and tilts backward. Nearby construction workers in high-vis vests panic and run to the right. The entire load of bricks then avalanches off the back of the trailer, crashing heavily onto the dirt ground. The bricks shatter and create a massive, billowing cloud of reddish-brown dust. The truck's suspension bounces up slightly from the sudden weight loss as it continues driving forward. Raw, realistic mobile footage style, natural lighting, continuous shot.
