# ============================================================
# Demo App — Cloud Run CPU Service
# Serves the UI and proxies /analyze requests to the vLLM GPU service.
#
# nginx starts instantly on port 8080 (serves UI from filesystem),
# uvicorn loads in the background (~20-30s) and handles API calls.
