/* Страница решения «Телеметрия сельхозтехники через ISOBUS» (solution-isobus.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 приборов (терминал, табло,
   журнал) всегда тёмные, как у настоящих устройств.
   Интерактив — solution-isobus.js. Без скрипта (нет класса .isb-js на <html>)
   все вкладки и состояния показаны сразу, страница остаётся полной. */
