/* ZAD — a bilingual edition.
   The page is set like a printed book: one measure, ruled entries, gold used
   only where the logo already uses it. Arabic leads, English follows after the
   colophon rule, so a reader of either language gets a whole page rather than
   a translation hidden behind a toggle. */
