Configuration

Backend .env

USERNAME=your_username
PASSWORD=your_password
VEHICLE_REGISTRATION=4SH1148

Variance Parameter

Controls kilometer distribution randomness:

• 0.0 - Equal distribution
• 0.1 - 10% variance (recommended)
• 0.2 - 20% variance (more random)

Future Enhancements (Phase 2)

• 📊 Dashboard with statistics
• 📈 Fuel efficiency charts
• 💰 Cost tracking
• 🗺️ Route history
• 📑 PDF reports
• 🔐 User authentication
• 💾 Database persistence

Migrated Features

All functionality from original 3-script pipeline:

1. ✅ knihajizd.py → scrapers/
2. ✅ fill_table.py → calculators/
3. ✅ fill_web.py → Future: Playwright automation
