structured blocks, diffs against current blocks, and records patches
- Frontend: new Preview tab shows live PDF rendered from the authenticated
endpoint (blob URL via fetch with auth header)
- Frontend: Upload DOCX (arrow-up) button in action bar sends the file to the
branch, backend computes diff automatically
