Greptile Summary

• Comparison content covering eleven platforms.
• FAQ metadata for page rendering and structured data.
• Updated title, description, introduction, and table with a consistent platform count.
• A Season Sans cover image for the article.

Confidence Score: 5/5

This looks safe to merge.
