   Vindex Studio — Pregled portfolija (/portfolio/) — Korak 30 premium
   redizajn. Sve novo pravilo ovdje ide POD .page-portfolio (klasa na
   <main>) — bez utjecaja na druge stranice. Napomena: .portfolio-filter__btn
   i .portfolio-card/.portfolio-grid dijeli i blog (filter) te service-detail
   ("Povezani projekti") — zato SVE nadogradnje izgleda ovdje idu isključivo
   kroz ".page-portfolio " prefiks, nikad na goli selektor.

   Sadržaj:
   1. Scroll-reveal osnova (.portfolio-reveal-up/-card/-stagger)
   2. Lokalni wrapper + eyebrow marker + pozadinski ritam
   3. Uvodna sekcija
   4. Filtri (premium izgled)
   5. Gridovi (standardni + istaknuti red)
   6. Kartica projekta — vizual, hover, status bedž, oznake, CTA
   7. Sekcija "Projekti u razvoju"
   8. Responsive
   9. prefers-reduced-motion
