/* === IKONICE ============================================================
   Ranije se ucitavao ceo Font Awesome sa cdnjs-a: all.min.css (102 KB) plus
   tri fajla fonta. Od svega toga koriscene su 42 ikonice.
   Sada stoji samo ovo: jedan lokalni fajl fonta i 39 pravila ispod.
   Time nestaje i treca strana sa kriticne putanje (DNS + TLS ka cdnjs-u),
   a sa njom i sva njihova @font-face pravila sa font-display:block, zbog
   kojih su ikonice umele da budu nevidljive do 3 sekunde.

   Tri znaka drustvenih mreza (Facebook, Instagram, TikTok) su ubacena pravo
   u HTML kao SVG - zbog njih se skidao ceo Brands font od 108 KB.
