   «Бизнес, ИИ и человек: что усилить в 2027 г.?» — /ai-conf-2026-dec/assets/css/style.css
   Промо-лендинг конференции 14.12.2026, статичная страница вне шаблона сайта (своя шапка, подвал,
   прелоадер), префикс ac-. В сборщик шаблона не входит. По структуре повторяет лендинг /ai-conf-2026/ (сентябрь), палитра —
   фиолетовая по программе конференции (PDF): глубокий фиолетовый фон, световые вертикальные
   линии на canvas, светлые карточки программы (крем / голубой / зелёный). Лёгкий снег — декабрь.
   Блок «Как это было» — видео и фото сентябрьской конференции (файлы из /ai-conf-2026/assets/, превью в assets/img/was/).
