/*
 * core.css — стили страниц нового ядра (public_html/src, Twig-шаблоны с {% extends 'layout/core.twig' %}).
 * Живут внутри старой шапки (Bootstrap 2 + jQuery), поэтому всё — внутри контейнера .core, классы с префиксом core-,
 * а унаследованные правила Bootstrap 2 (высота и отступы инпутов, label block, line-height заголовков) сбрасываются ниже.
 * Без фреймворков и сборки: CSS-переменные, grid/flex, адаптивность от 360 px до широкого монитора.
 *
 * Поддержка браузеров (решение по данным участников, вики «Вёрстка нового профиля», 20.10.2026): Chrome и браузеры
 * на его движке (Яндекс, Opera, Edge), Firefox, Safari на macOS и iOS — версии за последние 2–3 года
 * (Chrome/Edge ≥ 110, Firefox ≥ 110, Safari ≥ 16); Internet Explorer не поддерживается.
 * Поэтому допустимы: CSS-переменные, grid, gap, :is()/:where(), min()/clamp(), accent-color, :focus-visible, inset.
 *
 * Разделы: 1 переменные и базовый контейнер; 2 сброс наследия Bootstrap 2; 3 сетка и карточки; 4 формы;
 * 5 кнопки; 6 уведомления; 7 таблицы и списки; 8 переключатель; 9 утилиты; 10 адаптивность.
