# Sales Trainer — single-container runtime (Python 3.11 + Flask)
#
# The Vue frontend is BUILT LOCALLY (`cd frontend && npm run build`) and the
# resulting `frontend/dist/` is committed to the repo. This image does NOT run
# npm/node at all — it just copies the prebuilt SPA and serves it via Flask.
# This eliminates `vite: not found` / npm postinstall flakiness from the build.
#
# To update the UI: edit frontend/src, run `npm run build` locally, commit dist/.
