   Dôvod: backdrop-filter/transform na #navbar by vytvorilo nový "containing
   block" pre position:fixed potomkov (.nav-links mobilné menu), čím by sa
   menu prestalo správne fixovať na celú obrazovku a pri scrolli by sa
   posúvalo/rozpadávalo. Pseudo-element nie je v tomto zmysle "rodič", takže
   menu zostane vždy fixované na viewport. */
