   ЦИФРУС · admin · login screen — Industrial Brutalism
   Подключается ТОЛЬКО на login.html. Остальные admin-страницы пока
   живут в editorial-стиле (main.css) — редизайн в Шагах 8.2-8.7.
   Берём brand-канон из tokens.css (--bg, --ink, --shadow, --font-display
   и т.д.). Внутри scope `.body-login` — чтобы не конфликтовать
   с .btn/.field admin'а.
