 * Блок calculator (blocks/calculator.php): калькулятор стоимости, дизайн — набор medwebika-calculator-v2-assets.
 * Карточки: .calc__opt → скрытый нативный input + .calc__opt-body (значок, название, отметка).
 * Колонки — по числу вариантов (--n из шаблона, в медиа-запросах меняется --cols), ниже 1150px шесть карточек встают по три, ниже 760px — по две.
