The translated twins of this section (or, on the home page, of the book): read
it side by side with the English in the reader, or download the twin PDF, or
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, read_url}], from
views._translation_links; sbs_url is "" when the sheets are not on disk, and
read_url is "" where there is no reader (the home page). In the bar, each entry
also has here_url (this view, with that translation), `twin` is the entry shown
beside the English now (or None) and english_only_url goes back to the English
alone.
