Use the supplied image as the exact first frame. 0–1s: the pen tip pauses above the notebook. 1–4s: the right hand naturally writes about two short lines while the man makes one very small nod. 4–5s: the pen stops and he continues looking at the notebook. Add a very slow over-the-shoulder camera push-in. Keep his face hidden. Any newly written marks must remain abstract, unreadable handwriting texture, not legible words. Preserve the chart screens and all existing props. No finger deformation.
