/* =============================================================================
   Z. Aliases & admin-engine pages (W1.4 hotfix)
   Назначение: страницы worker-diag / generations / queue использовали классы,
   которых не существовало в основной таблице стилей (card__body, data-table,
   table-wrap, btn-warning, btn-info, btn-success, diag-tile). Из-за этого
   они выглядели «как будто без вёрстки». Добавляем алиасы и недостающие
   стили – старые шаблоны заработают без правок.
