/* Rýchly nákup z karty produktu
   ---------------------------------------------------------------------------
   Oranžové tlačidlo košíka na karte otvorí toto okno, kde si zákazník vyberie
   farbu aj veľkosť a pridá kus do košíka bez opustenia výpisu.

   Vzhľad je zhodný s rýchlym náhľadom „Super set" na produktovej stránke, ale
   komponent je zámerne samostatný (vlastné triedy `.bh-kv`, vlastné premenné),
   aby sa dal načítať na kategóriách a homepage bez celého product.css. */
