# IntelliCredit-CreditAppraisal-v2.0 — HuggingFace Spaces Dockerfile
# Docs: https://huggingface.co/docs/hub/spaces-sdks-docker

# This image runs ONLY the environment server (FastAPI + uvicorn).
# GRPO training happens on a separate GPU machine — not here.
# The .dockerignore excludes training/checkpoints, evaluation/results, etc.
