   АМФОДЕНТ — ТЕМА «КИНЕМАТОГРАФИЧНЫЙ ПОСТЕР» (мягко осветлённая: графитово-голубой фон)
   Тёмная версия лендинга поверх css/style.css + css/landing.css. Ничего не
   удаляет и не переопределяет логику: только палитра, типографика и
   декоративный слой (в т.ч. «матовое стекло» калькулятора). Подключается
