## Checks before you return it
1. Every word on the package matches the flat art letter for letter (read each line).
2. Layout matches: same order, same relative sizes, same colours (within normal lighting).
3. Art is flat and undistorted apart from natural curvature; edges and corners are not warped.
4. The package is believable: correct proportions, crisp edges, real material, consistent shadow.
5. No extra text, logos, barcodes or graphics anywhere, including the side and lid.
6. Props carry no readable text; nothing else in frame competes with the package.
7. Correct ratio, not upscaled, no watermark.
If check 1, 3 or 5 fails, do not call it finished. Maximum 3 attempts, then return the best and name what differs.
