# turnout uploads a `dist` directory as it finds it, so `dist` has to contain
# exactly what the remote build needs - not the repository root, which also
# holds `target/` (gigabytes of host-architecture artifacts) and, on a machine
# that has run the stand locally, a `.env`.
#
# `git archive` is the filter: it emits tracked files and nothing else, so a
# secret that was never committed cannot be uploaded by accident.
