/* === v1.51 kolaz: uređivanje kolaža u velikoj slici stranice oglasa ==========
   src/frontend/oglas/kolaz.css (HTML: src/frontend/oglas/kolaz-editor.mjs).
   Canvas kolaža (1600×1200) + sloj iznad njega: ćelije (povlačenje = izrez,
   izvan ćelije = zamjena mjesta; alati za podjelu u kutu), crte (ručka za
   povlačenje, × spaja dvije slike) i "duh" fotke koja se vuče. Desno izbor
   oblika (predlošci 2–6 + vlastiti). Boje kroz tokene; ručke i gumbi preko
   fotke su svijetli s tamnom sjenom (čitljivi na svakoj fotki, kao strelice
   pregleda slika). Učitava se u index.html iza analitika/analitika.css. */
