# (tsc -> /app/server).

# ---- Runtime stage --------------------------------------------------------
# Only ships what is needed to run: the compiled server, the built front and
# the resolved node_modules (kept from the build stage so transitive runtime
# deps such as tslib - used by the compiled server via importHelpers - are
# guaranteed to be present).
