EXIT to a blank corridor that may not exist

  "input": {
    "prompt": " Cinematic photo/illustration hybrid: a doorway labeled “EXIT” opens into an impossibly white, featureless corridor fading into overexposed nothingness. A suited figure (the Prime Minister from behind) steps through mid-stride, slightly silhouetted. The corridor has no doors, no lights—just clean, uncanny emptiness, reinforcing the final gag."
