/*
 * site.css — оформление сайта leo-wend.ru (редизайн 13–14.10.2026).
 *
 * Владелец: «полный редизайн, сайт выглядит ИИшным» → затем: «дизайн сделай крутым, много анимаций, а не
 * минимализм; тема тёмно-синяя и бело-синяя». Две темы: светлая — белая с синим, тёмная — глубокий тёмно-синий.
 * Узкий жирный Ubuntu Sans в заголовках, моноширинный — в подписях и цифрах. Движение: появление блоков при
 * прокрутке, счётчики, бегущий ряд силомеров, смена цвета силомера на первом экране, наклон за мышкой
 * (static/js/site.js). При «уменьшить движение» в системе анимации выключены.
 *
 * Шрифты — свои, со своего сервера (static/vendor/fonts, Ubuntu Sans, лицензия Ubuntu Font Licence):
 * внешние CDN без VPN у части провайдеров не открываются.
 * Тема — класс .dark/.light на <html> (переключатель в шапке) или настройка системы.
