// The Money sample, written the way each language writes it. Its three
// stored amounts are the same on every page and the currency codes never
// change; what changes is how the reader's language writes them, which
// is the whole of what the sample shows. Fiesta has no currency
// formatter and does not grow one for a sample, so the markup is
// Rastrillo's: hack/seed/run-translations.sh writes moneySampleMarkup's
// output for each of the twelve locales into i18n/money.json. The
// English entry is the seeded example's body, which
// TestTheMoneyTableStartsFromTheExample holds.
//
// The markup bypasses localMarkup, as Rastrillo's formatMarkup does: it
// is already written for its locale, and its ISO codes read as words to
// hasWords, so the parity gate would ask for eleven translations of a
// code that must never change.
