# SET50 alternative-data platform - single-container image.
# Serves: built Vue SPA (frontend/dist) via nginx, proxying /api to the
# Flask backend (127.0.0.1:5000). Data persists under /app/backend/data
# (mount a volume there or set DATA_DIR to a mounted path).
#
# Build strategy: PREBUILT frontend dist (no node/npm/vite in this image) —
# build with `cd frontend && npm run build` and commit frontend/dist/.
