/* ============================================================================
   База знаний — надстройка над дизайн-системой продакшена.

   Всё общее (цвета, шрифты, кнопки, поля, карточки, вкладки, меню, таблицы)
   приходит из `tokens.css`, `base.css`, `components.css` и `erp.css` без
   изменений. Здесь только блоки, которых в работающей системе нет, и все
   они под своими именами: `kn-learn-*` — обучение, `kn-ai-*` — помощник.
   Второе правило с именем продакшена молча переписало бы чужой экран.

   Правило отступов: расстояние между блоками задаёт сам блок, а не место
   вызова. Блоки верхнего ряда страницы отбиваются снизу на 16 px — как
   `.kn-todo` и `.kn-dash-grid` продакшена; внутри стопок и сеток отступ
   держит `gap`, и собственные поля там гасятся.
