/**
 * Bootstrap 5.3.9 (файлы темы, vendor/bootstrap — из пакета npm bootstrap@5.3.9) — в слое bootstrap: стили темы (вне слоёв) сильнее его при любом весе селектора.
 * Файл не объединяется с другими (preprocess: false в sn.libraries.yml): порядок слоёв задаёт первая строка.
 *
 * Разметка сайта пришла из D7 на классах Bootstrap 3, часть имён совпадает с Bootstrap 5, но значит другое (row,
 * nav, navbar, col-sm-6, form-text, placeholder…), а его правила для тегов меняют тексты материалов. Поэтому ниже для
 * каждого правила Bootstrap 5, которое задевает разметку сайта, стоит то же правило нулевого веса с revert: свойство
 * возвращается к значению браузера, дальше действуют css/skin.css и css/style.css. Классы Bootstrap 5, которых в
 * разметке сайта нет, работают как обычно. Список собран скриптом tools/theme/build-css.mjs (unleak).

/*
 * Правила Bootstrap 5 с !important внутри слоя сильнее любых стилей сайта; сильнее них — только !important в слое,
 * объявленном раньше. Так Bootstrap 5 прячет .visually-hidden: 1×1 пиксель, margin −1px, без отступов и рамки, без
 * переноса строк. У Drupal этот класс свой (system/hidden.module.css), и поверх него работают правила ядра и вида.
 * Ниже — то, что было до Bootstrap 5: служебный блок объявлений в конце страницы не укорачивает её на пиксель,
 * скрытые заголовки держат отступы вида, элемент с .focusable показывается по фокусу с клавиатуры, кнопка
 * контекстных ссылок сохраняет свой размер (contextual.theme.css, contextual.icons.theme.css).
