   Главная (index.html): виджет во всё окно ПОД шапкой (родной поток v0.0.2).
   Шапка остаётся сверху, ниже виджет занимает всю ширину и всю оставшуюся
   высоту; внутренний топбар, двухколоночное тело и панель «Что понял ИИ» —
   часть самого виджета (mode=fullscreen). Высоту виджета задаём как остаток
   вьюпорта минус шапка через --bs-fullscreen-block-size (наследуется в Shadow
   Root). Правила скоупом .page--widget, чтобы не задеть страницы документации.
