/* ===== Desktop =====
   ODSTRANENE: cely blok patril STAREMU bocnemu menu (.nav-link,
   .brand-text, .nav-text, .sidebar-footer) - tie triedy uz v markupe
   nie su, dnesny sidebar sa cely riadi z templates/base.html.

   Nebol ale neskodny: `.sidebar` sa vola rovnako aj dnes, takze
   pravidlo `.sidebar:hover, .sidebar:focus-within{ width: 280px }`
   na nase menu dosahovalo. A kedze `:focus-within` ma vyssiu
   specificitu (0,2,0) nez `.sidebar` v base.html (0,1,0), prebijalo
   ho: na tablete stacilo tuknut na polozku menu, fokus ostal v paneli
   a ten sa roztiahol z 215 na 280 px. Na pocitaci to vidno nebolo -
   tam ma base.html vlastne `.sidebar:hover` s rovnakou specificitou
   a neskorsim poradim, takze pri mysi nad panelom sirku drzalo ono.

   Ostatne `.sidebar` pravidla v tomto subore (farba textu, ramik,
   white-space) su stale v hre a base.html ich neprepisuje - preto sa
   odstranuje len tento blok, nie cela sekcia. */
