{#
    Landing page of a dataset.

    The page itself is rendered by Vue, which means that a client that does not
    execute JavaScript sees nothing but the app shell. For a *published* dataset
    that is a problem: its DOI resolves here, and this is where FAIR assessment
    tools, search engines and reference managers come looking for the metadata.

    Everything below is therefore rendered server-side, and only for published
    datasets: an unpublished one is not public and has nothing to advertise.
