# Hugging Face Spaces — docker SDK runtime for the health-marketing-compliance-rag
# FastAPI + React SPA application.
#
# Multi-stage build:
#   1. Node stage: builds the React frontend (frontend/dist/)
#   2. Python stage: installs Python deps via uv, copies frontend assets, runs uvicorn
#
# HF Spaces convention: app runs as user "user" (UID 1000) on port 7860.
