The daily cron (launchd on your Mac) runs tools/generate-llms-full.js at 3 AM. It:

1. Checks this toggle (via GET /public/settings) — skips if disabled
2. Reads llms.txt static base (teachers, pricing, FAQ — you maintain this)
3. Finds every blog/*/index.html and extracts the <main class="article-body"> text
4. Rebuilds the Blog Articles section only — static content is never overwritten
5. Uploads to S3 + invalidates CloudFront

To update teachers, pricing, or FAQ: edit llms.txt manually, then run the generate script to push.
