- Organize backend into src/ (routes/, services/, db/) per package.json entrypoint
- Add migrations/import-mdb.js for one-time .mdb → SQLite migration
- Add public/ frontend: check ledger table, slide-in new/edit panel, PDF generation
- Add docker/Dockerfile and docker-compose.yml for self-hosted deployment
- Add .github/workflows: Docker Hub build+push on main/tags, TODO→Issues scanner
- Add GnuMICR font files (GPL-2.0) for MICR E-13B line rendering
