## When to prefer this

Choose this endpoint when you need a deterministic, reproducible escaped HTML preview of a case study document and do not want any AI-generated prose or fact-checking. Prefer it over generative writing endpoints when auditability and consistency matter, and when the input is already written Markdown or plain text that simply needs safe HTML conversion for web embedding.
