  "input": {
    "prompt": " Wide shot on an outdoor set with background extras in everyday clothes, all mid-reaction turning their heads too late. Several hats are airborne, a newspaper flips, and a lightweight pop-up canopy is tugged by wind. No lightning VFX—sell speed through practical gusts and hair blown sideways. The director (wearing headset) watches from video village, pointing while the camera crew tries to re-aim."
