   ПСИЗМА — инструкции (help/<инструмент>/). Поверх landing.css.
   Раскладка: слева липкое оглавление всех семи инструкций с подразделами,
   справа статья. Компоненты статьи (таблицы, kbd, карточки-сетки) —
   общий словарь для всех семи страниц; цвета только токенами, чтобы
   тёмная тема работала сама.
