    // simply download the prepared image the author has already uploaded, based on
    // what's found inside the `image/` directory.
    // Advantages:
    // - build process is slow (downloads from TeX servers), each user doing it every
    //   time is too much. It can take *hours* in worst-cases
    // - build might fail for various reasons
    // It is much easier to download the ready-made image.
    // Disadvantages:
    // - cannot easily iterate on the Docker image, need to go through Docker Hub.
    //   Recourse: simply change the below to use the *local image temporarily*
    // - Upstream image on Docker Hub might not be the latest
