   Устойчивая версия: высота блоков с картинками (proof-
   карточки и compare-слайдер) держится на aspect-ratio +
   min-height + @supports-фолбэке, поэтому не схлопывается.
   Из секции пруфов убраны фичи, которые ломают композитинг
   в WebKit и встроенных браузерах (Telegram/соцсети):
   тяжёлый filter: blur(), isolation: isolate и вложенные
   backdrop-filter на карточках.
