    # Because we use one full CI run for a deployment of *each* instance (i.e. n deployments for n instances),
    # in order to deploy reasonably quickly, we assume the the Docker build caches intermediate layers across
    # CI runs.
    # The docker/build-push-action's GitHub caching option (cache-from, cache-to, see https://github.com/docker/build-push-action/blob/v4/README.md#customizing)
    # uses BuildKit's GitHub caching feature (https://github.com/moby/buildkit/blob/c81deef18855d952247915d3418371f405719a23/README.md#github-actions-cache-experimental),
    # which follows the general GitHub Actions caching restrictions (https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#restrictions-for-accessing-a-cache).
    # The means that Git tag CI runs *cannot* access each other's cached Docker layers, but only the default
    # branch's one. This is why, on the default branch (`bbnavi`), we *do* build & cache the Docker layers
    # but don't push and don't deploy the resulting image.
    # todo: as of 2023-04-27, this fails because of https://github.com/moby/buildkit/issues/2887
