Prompt

I run an online store selling handcrafted leather boots. Here is my product page content: title, price ($249), in-stock status, 45 customer reviews averaging 4.8 stars, and shipping info. Could you calculate my structured data readiness score and provide the exact valid JSON-LD code I should add to my site to help Google recognize it for rich product snippets?
