/* Страница решения «Данные CAN-шины» (solution-can.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. Приборная панель и экраны
   всегда тёмные, как у настоящей машины.
   Интерактив — solution-can.js. Без скрипта (нет класса .can-js на <html>)
   все вкладки и состояния показаны сразу, страница остаётся полной. */
