# ---------------------------------------------------------------------------
# EcoSync — single-image build for Google Cloud Run.
#
# Stage 1 compiles the React dashboard. Stage 2 installs the FastAPI backend
# and copies the built frontend into ./static so one service serves both the
# API (/api/v1/*) and the SPA. Cloud Run injects $PORT at runtime.
