/* Лендинг inapp (/landing/), вариант A (исходник и план - docs-project/landing-animated/).
   Токены цвета - те же значения, что у боевого /landing/ (catalog.css, body.landing-gradient):
   светлая и тёмная тема по системной настройке, без переключателя - как на боевом лендинге.
   Анимируются только transform и opacity. Скрытые начальные состояния - только под классом
   .la-js, который ставит скрипт в <head>; без JS и при prefers-reduced-motion всё видно сразу. */
