#  Selene ML APIs — Hugging Face Spaces Dockerfile
#
#  Serves BOTH the cluster (GMM) and simulator (HistGBM) models in a single
#  FastAPI process on port 7860 (required by HF Spaces).
#
#  Build & push via push_to_hf.sh — do NOT build from repo root directly.
#  The Dockerfile expects to run with build context = this hf_space/ directory.
#
#  Local test:
#    docker build -t selene-ml-apis .
#    docker run -p 7860:7860 selene-ml-apis
