Example prompt: Can you generate a paragraph change report comparing my updated project brief to the previous version? Here's the new text: '## Objective
Deliver a scalable platform by Q3.

## Scope
Includes backend and frontend work.' and the old text was: '## Objective
Earlier draft content.'

## When to prefer this

Choose this endpoint when you need a fast, deterministic, structured paragraph-level change report specifically for project briefs in Markdown or plain text format, and you want a consistent, template-driven output rather than AI-generated prose. Ideal for document versioning workflows, audit trails, and stakeholder communication where reproducibility matters.

## Known failure modes

- Missing or empty text field — no comparison can be performed
- Previous text not supplied — diff cannot be computed, may return empty or error
- Non-UTF-8 or malformed Markdown may produce unexpected output
