Description
Why
Columns drift when layouts change per page. We need to anchor to headers and realign.
Tasks
- Detect header row per page (fuzzy match against canonical header set)
- Map per-page headers → canonical order
- Snap column bounds to matched headers (with tolerance)
- Add unit tests + 2 real PDFs as fixtures
Acceptance Criteria
- Multi-page PDFs with shifting headers produce aligned CSVs (no column swaps).
