# Single-container image for a Hugging Face Space (Docker SDK).
#
# Spaces expose exactly one public port, but Auralynq's default topology is
# 7 containers behind a Caddy proxy (see containers/ and compose.yml). This
# image instead runs the API (FastAPI/uvicorn, loopback-only) and the web UI
# (Next.js standalone) as two processes in one container; Next.js itself
# proxies /api/* to the API process (see web/next.config.js's rewrites()),
# so no separate reverse proxy is needed.
#
# Build context must be the repository root:
#   podman build -f deploy/huggingface/Dockerfile -t auralynq-space .
