# Single image serving BOTH transports of the vgi-calendar worker:
#   docker run ... IMG            -> HTTP server on $PORT (default 8000; /health, VGI RPC)
#   docker run -i ... IMG stdio   -> stdio worker DuckDB spawns on-host
# See docker-entrypoint.sh. Everything is pure/offline (holidays + python-dateutil);
# no network, no model downloads, no persistent state.
