/* =====================================================================
   Сервис AmneziaWG — Octo-style dark SaaS dashboard theme
   Вдохновлён стилем octoclick: тёмно-синий уголь, округлые карточки 14px,
   тонкие полупрозрачные границы, синий акцент #2D7BFF, системный шрифт.
   Переопределяет Bootstrap на уровне CSS-переменных, чтобы все компоненты
   (кнопки, формы, алерты, таблицы, навигация) автоматически подхватили стиль
   без переписывания разметки.
