Auto-generate & publish SEO articles to WordPress with GPT-4 + Postgres tracking
🚀 What this flow does
• 🔎 Selects the least-used WordPress category (tracked in PostgreSQL)
• 🤖 Uses GPT (4-mini or better) to generate a fully formatted SEO article with headings, TOC, lists, CTA, and Yoast blocks
• 🖼️ Creates a placeholder cover image and uploads it to WordPress Media
• 📬 Publishes the final post via /wp-json/wp/v2/posts with correct category + featured image
• 🧠 Logs the used category for future rotation (zero duplicates!)
