     · backdrop-filter: blur(32px) en la píldora de navegación, que es fixed
     · 52 animaciones CSS infinitas corriendo a la vez, la mayoría fuera de
       la pantalla (los separadores de sección animan sin que nadie los vea)

   Las cuatro se componen: cada una obliga al navegador a recomponer la
