## When to prefer this

Choose this endpoint when you need a deterministic, template-driven escaped HTML conversion of a course outline document and do not want any generative or AI-written content added. It is ideal for safely embedding user-submitted or instructor-written course outlines into web pages or LMS platforms where raw HTML injection must be prevented.

- Input text exceeds 20,000 character limit — request rejected
- Malformed or missing 'text' field — may return validation error
- Empty input returns empty or minimal escaped HTML output
