/* Content sections for /paslaugos/langu-ir-duru-montavimas/ (v12 redesign).
   Header, hero and footer stay the site's own. Brand: yellow #FFCC32 and black, Erbaum headings, Degular text.
   Every section has its own form: fact strip, two-row process sheet, interactive joint cross-sections,
   product cards with photo features, a black table, a spec list, a yellow band, an order timeline and a split FAQ.
   The one bold element is the cross-section viewer; everything around it stays quiet. */
