   prAIme — zajedničko zaglavlje i podnožje za CIJELI sajt.

   Jedan izvor istine za chrome. Prije ovoga postojala su četiri različita
   para zaglavlje/podnožje: landing (tamno podnožje), blog (svijetlo, drugi
   logo), SEOLayout u React aplikaciji (treći raspored, ekavica „Cene") i
   Comparison sa sopstvenom navigacijom. Sada svi koriste ove klase.

   Vezuje se sa:
     - statičke stranice:  <link rel="stylesheet" href="/site-chrome.css">
     - React aplikacija:   isti <link> u public/index.html; SEOLayout
                           renderuje isti markup sa istim klasama.

   Markup zaglavlja (identičan svuda):
     <header class="pr-nav" id="prNav">
       <div class="pr-wrap pr-nav-in">
         <a href="/" class="pr-brand"><img src="/logo.png" alt="prAIme"></a>
         <nav class="pr-nav-mid"> …linkovi… </nav>
         <div class="pr-nav-right"> …dugmad… <button class="pr-burger"> </div>
       </div>
     </header>
