FIRST REQUEST
Create an animated GIF from this product image using the native image/GIF creation feature. Keep the bottle shape, green color, cap, cream background, label and the exact text MORROW, COLD BREW and $18 unchanged. Animate only a small soft highlight moving once across the bottle, returning to the starting state in a seamless loop. Fixed camera, no rotation, no zoom, no added objects. Aim for a 2-second square looping GIF. Return the actual downloadable animated GIF, not a static sprite sheet. Do not use Python, code, an external API or a video tool to assemble it.

PRICE REVISION
Make one targeted revision to this GIF: replace the price "$18" with "$16" in every frame. Preserve MORROW and COLD BREW, the bottle silhouette, cap, label position, background, fixed camera, highlight animation and looping behavior. Return the revised downloadable animated GIF using the same native GIF feature. Do not assemble it with code or use an external API.
