/**
 * Which button actually CLOSES the form on this confirmation?
 *
 * 1C asks two different questions with the same two buttons:
 *   «Данные были изменены. Сохранить изменения?» → Да = save+close, Нет = close without saving
 *   «Виза сохранена не будет. Закрыть согласование?» → Да = close, Нет = STAY IN THE FORM
 * A hard-coded «Нет» for save:false is right for the first and exactly backwards for the second:
 * the caller asks to close and gets a form that stays open (measured — that is how a modal leaked
 * into the next test).
 *
 * Decide by the QUESTION, not by the whole message: both texts contain the root «сохран», but only
 * the interrogative sentence says what the buttons mean. Unknown wording keeps the legacy answer.
