Example prompt: Can you generate a paragraph change report comparing my updated campaign brief to the previous version? Here's the new text: '## Audience
Millennials aged 25-35.

## Message
Emphasize sustainability and value.' And the old version was: '## Audience
General consumers.'

Choose this endpoint when you need a deterministic, reproducible paragraph-level diff of a campaign brief document and want a structured change report without any AI-generated prose. Ideal for audit trails, review workflows, or automated change tracking pipelines where consistency matters more than generative summarization.
