5. Login with your master password

### NFO Metadata Setup (Optional)

For automatic NFO file generation with metadata and images:

## Technology Stack

- **Web Framework**: FastAPI 0.104.1
- **Database**: SQLite + SQLAlchemy 2.0
- **Auth**: JWT (python-jose) + passlib
- **Validation**: Pydantic 2.5
- **Logging**: structlog
- **Testing**: pytest + pytest-asyncio

## Application Lifecycle

### Initialization

On first startup, the application performs a one-time sync of series from data files to the database:

1. FastAPI lifespan starts
2. Database is initialized
3. `sync_series_from_data_files()` reads all data files from the anime directory (creates temporary SeriesApp)
4. Series metadata is synced to the database
5. DownloadService initializes (triggers main `SeriesApp` creation)
6. `SeriesApp` loads series from database via service layer (not from files)

On subsequent startups, the same flow applies but the sync finds no new series. `SeriesApp` always initializes with an empty series list (`skip_load=True`) and loads data from the database on demand, avoiding redundant file system scans.

### Adding New Series

When adding a new series:

1. Series is added to the database via `AnimeService`
2. Data file is created in the anime directory
3. In-memory `SerieList` is updated via `load_series_from_list()`
