   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>

/* =============================================================================
   TEMA — svijetla / tamna

   Prekidač postavlja data-theme na <html>, a izbor se pamti u localStorage
   (ključ pr-theme). Bez izbora se prati prefers-color-scheme. Skripta koja
   to radi mora biti INLINE u <head>, prije prvog crtanja, inače stranica
   bljesne svijetlo pa se prebaci.

   Statičke stranice ne dijele jedan skup varijabli — landing ima svoj :root,
   blog stranice `.blog-page`/`.blog-post-page`, a dokumentacija `dok.css`.
   Zato se ovdje prepisuju varijable svake grupe; sadržaj ih onda sam prati.

   dva stoje u `<span class="accent">` sa sopstvenim plavo-mint gradijentom,
