System Primer — Read Me First

This describes the system in 60 seconds.

• WordPress is NOT used for AI.
• All AI runs on Vercel.
• All embeddings + metadata are stored in Supabase.
• Source of truth is a nightly spreadsheet containing image URLs.
• Images get:
• embedding generated ONCE
• description generated many times
• Client reviews only hard images.
• Admin controls batches, prompts, and WP pushes.
• WP only receives final text field updates.

Core loop: Spreadsheet → Embeddings → Descriptions → Review → Prompt Evolution → WP
