   СТРУКТУРА: первый <strong> — заголовок карточки (display: block, отдельная строка).
   Любые <strong> после — обычный inline-bold в теле текста. Селектор `:first-child`
   применяет block-стиль ТОЛЬКО к заголовку, чтобы inline-bold в теле не ломал верстку.
   Пример:
     <div class="warning-card">
       <strong>Заголовок карточки</strong>            ← станет блочным
       Тело текста с <strong>inline-bold</strong>.    ← останется inline
