Create an 8-10 second sandstorm vehicle chase prompt set on a controlled closed desert route. Build it as a reusable video brief with three concrete beats: open on a lead vehicle cutting across dunes as a sand wall rolls in behind it; move into a low tracking chase where a second editable vehicle appears through dust, tire spray, and shifting sunlight; end on a stable hero frame as both vehicles break out of the storm with clear spacing and the horizon visible. Specify pacing, lens feel, camera distance, chase direction, dust density, light shafts, motion blur, tire track continuity, and rules that keep the action readable. Keep all vehicles, drivers, markings, terrain details, text, and logo areas editable. Avoid real brand names, celebrity references, fixed IP, unsafe public-road action, collisions with people, non-editable readable signage, sudden teleport cuts, inconsistent vehicle scale, impossible physics, and unrelated extra scenes.
