# An allowlist rather than an .assetsignore denylist: everything that lands in
# dist/ becomes publicly readable, so it should be a deliberate list, not
# whatever happens to be sitting in the working directory.
#
# The catch with an allowlist is forgetting to add a new module, which breaks
# the deploy outright (the import 404s and nothing loads), so the check at the
# bottom fails the build if any top-level .js file was left out.
