/* ЭКОТЕХ · международная версия 1.0 · на токенах DS 2.2.3 (tokens.css, PRODUCTION FROZEN).
   Концепция: «инженерный протокол» — тёмные разделы цвета графита (#0E1F3D) чередуются со светлыми;
   единственный смелый жест — живой фон первого экрана: потоки воды, тепла и данных вокруг знака ЭКОТЕХ.
   Все направления — логические свойства (RTL для ar/fa работает без отдельной таблицы стилей). */
