/**
 * One message in every language Wellformed speaks, side by side.
 *
 * A message is a string, or — where a language needs to count, reorder or
 * inflect — a function returning one. The function form is the whole plural
 * system: `(n) => n === 1 ? 'row' : 'rows'` needs no grammar engine, and each
 * language writes its own arithmetic, because "1 bestand, 2 bestanden" and
 * "1 file, 2 files" do not have to agree on anything but the argument.
 *
 * Keeping the languages beside each other in one entry, rather than one file
 * per language, is deliberate: a key cannot exist half-translated, the
 * compiler enforces it, and a reviewer sees both texts in one glance.
