/* Страница решения «Системы контроля высева СКИФ» (solution-skif.html).
   Подключается только на ней, общий styles.css не меняет. Все цвета схем —
   переменные темы, поэтому SVG сами переключаются между светлой и тёмной
   схемой вместе с сайтом. Экраны устройств всегда тёмные. Интерактив —
   solution-skif.js. Без скрипта (нет класса .skf-js на <html>) всё
   содержимое видно сразу. Общие блоки собраны из шаблона skf_build.py. */
