HTML document

Turn one complete Markdown PRD or technical design into one verified static HTML page. Keep Markdown canonical. Change presentation, not meaning.

Boundaries

• Accept an existing Markdown file or exact inline Markdown.
• Support only prd and design document kinds.
• Infer the kind only from the exact basename prd.md or design.md. Otherwise require the user or request to name it.
• Do not write requirements, settle design choices, summarize missing content, or edit the source.
• If the source is only a rough brief, use the appropriate authoring skill first.
• Do not hand-edit generated HTML. Change the template or renderer, then regenerate.
• Do not publish or host the result unless the user separately asks.
