        Transform this blog title: \"{blog_title}\" 

        Into a complete Pinterest marketing package. For each of the 5 variations, provide:

        1. Pinterest Title: Highly engaging, under 60 characters when possible
        2. Pinterest Description: 150-300 characters with targeted keywords
        3. Benefit or Hook: A specific, compelling benefit statement
        4. CTA Button Text: Action-focused text for the button (e.g., \"Learn More\", \"Try This Recipe\")
        5. Social Proof Statement: A line that builds credibility (e.g., \"Loved by 5,000+ home fermenters\")
        6. Pinterest Tags/Keywords: 5-7 relevant keywords (comma-separated)

        Format each variation as a JSON object with these fields:
        - title
        - description
        - benefit_hook
        - cta_button
        - social_proof
        - tags
