    # A new Joomla opens its web installer to whoever comes first. So the image's entrypoint is
    # run first only to copy Joomla into the volume and make the database, Joomla's own CLI
    # installer then makes the site and its Super User from the fields, and Apache starts only
    # once the site is installed: a refusal (Joomla takes a password of 12 characters at least)
    # stops the start, says why in the logs, and is tried again at the next.
    #
    # PHP's own upload limit is 2 MB, too little for a photo, and the image has no variable for it.
