   HELP-VIVO · NAV (MOBILE POLISH · V6 — TELEPORT + SMOOTH SUB)
   - Nema CSS skrivanja header menija/auth → fallback uvek radi
   - Na mobilnom: JS PREMESTA .c-menu__list i .c-auth u drawer (bez dupliranja)
   - Na desktopu: JS vraća 1:1 na originalno mesto
   - “Podrška” podmeni: glatko otvaranje/zatvaranje (height animacija)
   - Overlay, body-lock, focus trap, pristupačnost
