Animate the supplied original image as a premium five-second website hero visual. A refined warm reflection travels across the exact gold pen and paper while a soft shadow changes. Pen and notebook stay stationary and rigid; no writing. Preserve original composition, identity, materials and palette. Locked camera, no zoom, no cuts, no added text, logos or UI. Restrained continuous physical motion, no jitter or distorted objects. Aim for a similar first and last composition suitable for a soft loop.
