 * Blanc Minimal — единый завершающий слой действующего статического сайта.
 * Источник токенов: исследование/дизайн-системы-RAD-119/blanc-minimal/DESIGN.md.
 * Подключать ПОСЛЕ styles.css и ВСЕХ CSS конкретной страницы, без @layer:
 * прежние нелayered-правила иначе получили бы больший приоритет.
 *
 * Интерфейс не зависит от внешних ресурсов. Inter / JetBrains Mono используются
 * только при наличии на устройстве; системные fallback обязательны.
 * Тексты, адреса, логотипы, схемы и DOM не изменяются.
 * Десктопный rail сохраняется от 761px; mobile заканчивается на 760px.
 * Без JavaScript мобильная навигация раскрыта. has-js устанавливает оболочка.
 * Контрольные ширины для визуальной приёмки: 320 / 375 / 390 / 768 / 1024 / 1440.
 * Этот файл задаёт адаптивные состояния, но сам по себе не доказывает рендер.
