"""
Curatarr — Spotify History Importer (CLI wrapper)

The importer lives in ``src/services/spotify_import.py`` and is normally
driven from the GUI: drop the extended-streaming-history files (or the whole
zip) into Setup → Import or Admin → Spotify history import, pick the user,
done. This wrapper keeps the terminal path for headless boxes:

    python import_spotify.py <directory> [--user 1]

``<directory>`` holds Streaming_History_Audio_*.json / endsong_*.json files
straight from Spotify's privacy export.
