Links to the translated twins of this section (or, on the home page, of the
book): each language's twin PDF, and the English and twin side by side on
landscape sheets. Renders nothing when there is no twin this reader may have.

`variant` picks the setting: "rail" (the section rail's card), "bar" (the PDF
view's exits) or "home" (under the full-book link).

Context: translations — [{language, name, pdf_url, sbs_url}], from
views._translation_links; sbs_url is "" when the sheets are not on disk.
