## [Unreleased]

### Changed
- **Repository Structure**: Converted to multi-project monorepo
  - `web-app/` - Main Next.js application (formerly root directory)
  - `housekeeping/` - Database backup and maintenance scripts
- **Docker Configuration**: Updated Dockerfile and docker-compose files for new directory structure
- **Documentation**: Updated README.md and CLAUDE.md to reflect new structure

### Migration Notes
- All application code moved to `web-app/` directory using `git mv` to preserve history
- All database backup scripts moved to `housekeeping/` directory
- Each project is self-contained with its own package.json and dependencies
- Docker builds install dependencies from `web-app/` directory
- Volume mounts in docker-compose updated to reference `web-app/etc/hosts/`
- `.gitignore` updated to handle `node_modules` at any directory level
- No workspace management - each project is completely independent

## [2.17.0] - 2025-12-21

### Changed
- **PDF417 Barcode Generation**: Reverted from zxing-wasm library to pure JavaScript implementation due to barcode scanner compatibility issues. The barcodes generated by the zxing-wasm library were unreadable by scanners at "Tisak" kiosks in Croatia. The legacy custom PDF417 generator now ensures better compatibility with retail payment scanning infrastructure.

### Technical Details
- Restored `app/lib/pdf/pdf417.ts` - Custom PDF417 generator library
- Restored `app/lib/pdf/renderBarcode.ts` - Canvas-based barcode renderer
- Restored `app/ui/Pdf417Barcode.tsx` - React component using custom generator
- Updated all components to use legacy `Pdf417Barcode` instead of `Pdf417BarcodeWasm`

## [2.16.0] - 2025-12-20
