**Angular Downgrade:**
- Downgraded from Angular 20 to Angular 19 for better stability
- Updated all @angular/* packages to ^19.0.0
- Adjusted TypeScript to ~5.8.0 for Angular 19 compatibility
- Added required outputPath and index to angular.json for Angular 19 build requirements
- Verified production build works successfully
**NPM Registry Enhancements:**
- Updated Dockerfile.frontend to regenerate package-lock.json when custom npm registry is provided
- When NPM_REGISTRY is set to custom URL, the build will:
1. Configure npm to use the custom registry
2. Delete existing package-lock.json
3. Generate new package-lock.json with custom registry URLs
4. Run npm ci with the new lock file
- Default behavior (npmjs.org) unchanged - uses existing package-lock.json
**Build Verification:**
- Local build tested: ✓
- Docker build tested: ✓
- Bundle size: 348.75 kB raw, 91.73 kB gzipped
- No vulnerabilities found
**Usage:**
```bash
# Default registry (uses existing package-lock.json)
./quickstart.sh
# Custom registry (regenerates package-lock.json)
NPM_REGISTRY=http://your-npm-proxy:8081/repository/npm-proxy/ ./quickstart.sh
```

Implemented a complete Angular 20 migration with modern standalone components architecture and production-ready Docker deployment:
**Frontend Migration:**
- Created Angular 20 application with standalone components (no NgModules)
- Implemented three main components: artifacts-list, upload-form, query-form
- Added TypeScript models and services for type-safe API communication
- Migrated dark theme UI with all existing features
- Configured routing and navigation between views
- Set up development proxy for seamless API integration
- Reactive forms with validation for upload and query functionality
- Auto-refresh artifacts every 5 seconds with RxJS observables
- Client-side sorting, filtering, and search capabilities
- Tags displayed as inline badges, SIM source grouping support
**Docker Integration:**
- Multi-stage Dockerfile for Angular (Node 24 build, nginx Alpine serve)
- nginx configuration for SPA routing and API proxy
- Updated docker-compose.yml with frontend service on port 80
- Health checks for all services
- Production-optimized build with gzip compression and asset caching
**Technical Stack:**
- Angular 20 with standalone components
- TypeScript for type safety
- RxJS for reactive programming
- nginx as reverse proxy
- Multi-stage Docker builds for optimal image size
All features fully functional and tested in Docker environment.
