/* =========================================================
   Multiview – 4 maty na żywo
   Układ sterowany WYŁĄCZNIE atrybutami:
     #app[data-layout="grid|focus|mobile"]
     #app[data-viewport="desktop|phone-portrait|phone-landscape"]
     .tile[data-slot="0..3 | main | hidden"]
   Kafelki są pozycjonowane absolutnie w procentach, więc zmiana
   układu to płynna animacja top/left/width/height – iframe'y
   YouTube zostają na swoim miejscu w DOM i nie przeładowują się.
