- extractPdfText now renders each page to JPEG via @napi-rs/canvas + pdfjs-dist (108dpi)
- field-placement.ts sends rendered page images to GPT-4o with vision (detail: high)
- AI can now visually identify underlines, signature blocks, date fields, initials boxes
- System prompt focuses on visual cues (blank lines, boxes) not text pattern matching
- Handles multi-field lines: separate fields for signature blank and date blank on same line

- Install @dnd-kit/core@^6.3.1 and @dnd-kit/utilities@^3.2.2
- Create FieldPlacer.tsx with DndContext, draggable palette token, droppable PDF zone
- Implements Y-flip coordinate conversion (screenToPdfCoords / pdfToScreenCoords)
- Fetches existing fields from GET /api/documents/[id]/fields on mount
- Persists fields via PUT /api/documents/[id]/fields on every add/remove
- Renders placed fields as absolute-positioned blue-bordered overlays with remove button
- Default field size: 144x36 PDF points (2in x 0.5in at 72 DPI)
- Created src/lib/pdf/__tests__/prepare-document.test.ts with 10 test cases
- Tests verify Y-axis flip: screenY=0 → pdfY≈792, screenY=792 → pdfY≈0
- Tests verify scale-invariance at both 1:1 and 50% zoom ratios
- Installed jest, ts-jest, @types/jest and added jest config to package.json
- All 10 tests pass

Neon serverless driver requires remote WebSocket — incompatible with local
PostgreSQL. Replaced with postgres.js (drizzle-orm/postgres-js) in db/index.ts,
scripts/seed.ts, and drizzle.config.ts.
