# Expects ``meshchatx/public/`` to already contain a prebuilt frontend bundle
# (downloaded from the reusable Frontend build workflow), so this script only
# rebuilds the cx_Freeze backend before running ``electron-forge make``.
#
# Required system packages (installed by the workflow):
#   - snapcraft (installed via ``snap install snapcraft --classic``)
#   - LXD or multipass when building outside ``--use-lxd``/``--destructive-mode``
#     (electron-forge invokes snapcraft itself; we set
#     ``SNAPCRAFT_BUILD_ENVIRONMENT=host`` so the snap is built directly on the
#     runner without needing a build VM).
