博物館機器人的展廳追逐

A tiny museum security robot rolls through a moonlit gallery after closing, pauses beneath a suspended whale skeleton, then spots a paper airplane gliding past a framed landscape. The camera tracks low beside it, rises over the robot as it follows the airplane through a doorway, and ends on a wide reveal of the empty glass-roofed atrium. Polished stop-motion miniature craft, brass details, soft pool lighting, shallow depth of field, 35mm lens. Audio: quiet wheel hum, distant rain on glass, one soft paper flutter.
