/* --- Правки поверх брифа (обоснование в task-6-report.md) ---
   1) order-form.js переключает order_type-поля через toggle('show') / aria-hidden,
      а данные CSS-классы в брифе не описывают скрытие — без .dynamic-fields все три
      блока показывались бы одновременно. Добавляем hide/show; в разметке
      #engine-fields/#machining-fields/#units-fields получают доп. class="dynamic-fields".
   2) order-form.js жёстко вставляет <i class="fas fa-...">, а FontAwesome CDN в новой
      редакции лендинга не подключается (см. index.html). Даём текстовый fallback через
      ::before, не трогая сам JS. */
