/*
 * НейроОфис: оформление клиента LibreChat v0.8.8. Подключается из index.html при сборке образа (docker/brand.mjs).
 * Разделы: карточка уточняющих вопросов; каталог агентов; пустой экран чата с агентом.
 *
 * Карточка уточняющих вопросов (ask_user_question).
 * Все правила привязаны к структуре компонента AskUserQuestions:
 *   корень   — div, у которого прямой потомок-контейнер содержит fieldset[tabindex="-1"][aria-labelledby]
 *              (такой fieldset в клиенте один — шаг пакета вопросов);
 *   панель   — .popover над полем ввода, внутри которой этот корень;
 *   итог     — свёрнутая карточка заданных вопросов в чате ([data-testid="ask-user-question-call"]).
 * Темы высокой контрастности (html.high-contrast) не затрагиваются.
