+## Docker targets and entrypoint modes
+
+The container uses entrypoint.sh and supports two main modes:
+
+- http: starts the FastAPI app.
+- celery: starts the Celery worker.
+
+Build local/test target (installs all dependency groups):
+
+docker build --target local_test -t comment-automation:local .
+
+Build production target (installs only non-dev dependencies):
+
+docker build --target production -t comment-automation:prod .
+
+Run HTTP app (default mode):
+
+docker run --rm -p 8000:8000 comment-automation:prod
+
+Run Celery worker mode:
+
+docker run --rm \
