/* ==========================================================================
   Content/ui/accounts.css (ui-scope.md §2.1 п. 4) — UI-кит ТГУ.Работы для ТГУ.Аккаунтов.
   Источник: tsu.employee/frontend/src (index.css, components/ui, components/layout).
   Подключение: в пакете ~/Content/ui после bootstrap.min.css 4.6. Если минификатор
   StyleBundle не справится с современным CSS (:where, color-mix), — Bundle без минификации.
   Правила файла:
   - все размеры в px: Site.css Аккаунтов ставит html { font-size: 14px } до 768 px;
   - токены --tsu-*, классы .tsu-*: имена Bootstrap 4.6 заняты (--primary, .btn, .card, .badge);
   - базовые стили действуют только внутри <body class="tsu">.
