   MOBILE / TOUCH — desempenho no Safari do iOS
   O Safari mobile trava (engasga no scroll ou mata a aba por
   memória) quando precisa recompor camadas position:fixed com
   filter: blur() e backdrop-filter a cada frame. Em telas
   pequenas / dispositivos de toque trocamos esses efeitos de
   GPU por equivalentes estáticos. O gradiente radial já é
   suave por natureza, então dispensa o blur; o backdrop-filter
   vira um fundo opaco. O desktop não é afetado.
