        prompt = """You are performing a visual quality-control check on an advertisement to verify its aspect ratio. Your task is to determine whether the design has the correct aspect ratio for its intended use.

COMMON ASPECT RATIOS:
1. 16:9 - Standard widescreen video, digital displays, YouTube, social media video
2. 4:3 - Traditional TV/computer monitors, some digital presentations
3. 9:16 - Mobile video, Instagram Stories, TikTok
4. 1:1 - Square format for Instagram, Facebook, Twitter
5. 21:9 - Ultrawide displays, cinematic video
6. 2:1 - Film, some social media platforms
7. 3:2 - Print photography, some display ads
8. 4:5 - Instagram portrait orientation
9. Custom ratios for specific ad placements (billboards, banners, etc.)

STEPS TO EVALUATE:
1. Look for any visible dimensions or aspect ratio information in the image
2. If dimensions are visible, calculate the aspect ratio
3. Determine the likely intended use of the advertisement (based on content or metadata)
4. Check if the calculated aspect ratio matches the standard ratio for that intended use
5. If no dimensions are visible, try to visually estimate if the overall proportions match common formats
6. If you cannot determine dimensions or intended use, state that "Aspect ratio could not be verified."

YOUR OUTPUT:
• State whether dimension information was visible in the image
• If visible, state the calculated aspect ratio (e.g., "16:9", "4:3")
• State the likely intended use of the advertisement
• State whether the aspect ratio "passes" or "fails" for the intended use
• Include a JSON code block with these fields:
{
  "dimensions_visible": true or false,
  "calculated_aspect_ratio": "16:9" or other ratio or "Unknown",
  "intended_use": "Social media video" or other use or "Unknown",
  "aspect_ratio_check": "Pass" or "Fail" or "Not applicable",
  "recommendations": ["List specific recommendations if applicable, else an empty array"]
}"""
