自拍转场：吉祥物突然现身

A short cinematic video clip: the subject holds up a phone taking a normal selfie in an ordinary daylight room, alone in frame. The camera then pushes in slightly and, in one smooth transition, a tall, slender, pastel-purple cartoon rabbit-like mascot character with oversized round eyes, a wide friendly cartoon grin, and smooth, toy-like 3D-rendered proportions is revealed standing directly behind the subject in the reflection or background where nothing was visible a moment before. Keep the lighting on the mascot consistent with the room's existing light source through the transition, smooth and deliberate pacing, no jarring cuts, no distorted motion, no readable text, no logos.
