docker/nginx.hf.conf

# ============================================================================
# HF Spaces nginx config — single-container variant.
# Difference from docker/nginx.conf: listens on 7860 (HF's expected port) and
# proxies /api/* to 127.0.0.1:8000 (same-container uvicorn, not a compose
# service name).
