/* Ulazna koreografija herojaa je namerno sabijena u odnosu na prvu verziju.
   Razlog je merljiv: LCP element na ovoj strani je .hero__sub (fotografiju
   Chrome ne uzima u obzir jer prekriva ceo vidljivi deo ekrana i tretira je
   kao pozadinu). Dok je kašnjenje bilo 0.6s + 0.9s, LCP je padao oko FCP +
   1050ms. Redosled i stepenasti ulaz su ostali isti, samo se sve dešava
   ranije — to je stvarno, a ne kozmetičko ubrzanje prikaza sadržaja. */
