   PLEVIX — horná navigácia
   ---------------------------------------------------------------------------
   Jedna hlavička pre celý web. Nie je to zoznam odkazov: pod Nástrojmi,
   Pre koho a Vzormi sa rozbalí panel s tým, čo tam naozaj je — 21 nástrojov
   po kategóriách, šesť profilov, šesť vzorov. Návštevník nemusí hádať, čo je
   za ktorou položkou, a nemusí kvôli tomu prejsť na ďalšiu stránku.

   Odkazy v hlavičke sú SKUTOČNÉ adresy aj bez JavaScriptu — panel je len
   nadstavba nad nimi. Bez skriptu funguje hlavička ako obyčajné menu.

   Svetlá téma je základ. Domovská má `data-pxn-theme="dark"`, ostatné
   stránky sa riadia prepínačom témy webu.
