Confusion

The prompt

Close-up of a young medieval monk with a tonsure at a candlelit scriptorium desk, staring at a glowing modern smartphone lying on his illuminated manuscript, painterly historical realism, locked camera. 0–2s: he leans in and peers at the device with curiosity. 2–5s: the screen lights up; his eyebrows draw together, his head tilts, and one eye squints. 5–8s: his mouth twists to one side and he looks up past the camera, utterly baffled. Throughout: warm candle glow, quills and ink pots, stone walls in soft shadow, the phone's cool light on his chin, fixed camera.
