# sync_pilot — Median Müzik · sync-licensing dashboard.
# Deployed to HuggingFace Spaces (Docker SDK).
#
# The deploy script (sync_pilot/scripts/deploy-hf.sh) copies the
# ``sync_pilot/`` Python package alongside this Dockerfile so that
# ``import sync_pilot.dashboard.app`` resolves from ``/app/sync_pilot``.
