 * и текущего вида. Стоило раскладке осесть между замером и жестом, и 34 экранных
 * пикселя превращались уже не в 50 единиц плана: ресайз коммитил не ту величину,
 * а свидетель сообщал об этом четырьмя немыми `expected true, got false`.
 * Раннер ловил это, локальная машина — нет.
 *
 * Координаты сюда передаются В ЕДИНИЦАХ ПЛАНА; `nudge` — добавка в экранных
