/* ============================================================
   HamikVPN — общий стиль раздела /blog/ (Статьи + Рекомендации).
   Переиспользует токены/паттерны из index.html (единый неподвижный
   фон, header/nav/footer, .qa-аккордеон), плюс новые классы для
   чтения длинного текста (.prose) и хаба (.hub-*).
   Подключается через <link rel="stylesheet" href="/assets/blog.css">
   на каждой странице /blog/*, чтобы не дублировать ~200 строк CSS
   в 11+ файлах.
