/* ============================================================
   Калькулятор стоимости доски — попап. Дизайн-система лендинга:
   бумага, орех, медный акцент; результат — тёмная панель.
   Компоновка плотная: попап целиком помещается в экран без прокрутки
   (при нехватке высоты calc.js уменьшает его через zoom).
