DOCX export

[TomMaSS]

Goal

Export a complete PRD as a formatted Word document. Product managers and executives expect Word files.

Backend

Install python-docx in api/requirements.txt.

Endpoint: GET /api/projects/{slug}/export?format=docx

When format=docx:

1. Load all sections ordered by sort_order
2. Build a python-docx Document:
   • Title page: project name, description, export date
   • Table of contents (built-in TOC field)
   • For each section:
     • Heading 1: section title
     • Status badge as inline text: "[APPROVED]" / "[DRAFT]" etc.
     • Content: convert markdown to docx paragraphs via markdown-it-py AST
     • Dependencies listed as italic paragraph
   • Appendix: dependency graph as text-based adjacency list
3. Return as application/vnd.openxmlformats-officedocument.wordprocessingml.document

Markdown-to-docx conversion priorities:

• Headings (##, ###) -> Word Heading 2, Heading 3
• Bold, italic -> Run formatting
• Code blocks -> Monospace font with light gray shading
• Bullet lists -> Word bullet list
• Tables -> Word tables
• Links -> Hyperlinks (or plain text with URL)
• Anything unconvertible -> render as plain text (no crashes)

Frontend

Add "Export DOCX" option in the project export dropdown alongside existing PDF and Markdown exports. Triggers a download.

Acceptance Criteria

• Generated .docx opens in Word, Google Docs, LibreOffice without errors
• All sections present with correct content
• Markdown formatting (bold, lists, code blocks) renders correctly
• Status badges visible
• File downloads with correct filename
