Use the supplied image as the first frame. Preserve the exact fictional cobalt bottle, silhouette, material, dark ribbed cap and cream circular mark. Vertical 9:16, one continuous five-second product shot, no cuts, people, hands, invented labels, new parts, text, particles or liquid. The bottle remains closed, rigid, upright and stationary. SHOT: Locked camera on the cap and shoulders. One broad soft highlight moves gently across the bottle from screen left to screen right, revealing its matte surface and ribbed cap. The product does not move or deform. Keep the exposure stable.
