/**
 * Auth modali + header dugmad — frontend stil za Login/Register feature.
 *
 * Dizajn se oslanja na brand gold paletu (--gold #C8963E) iz main.css.
 * Modal patern je industry standard:
 *   - fixed overlay sa blur background-om (backdrop-filter)
 *   - centriran content sa fade-in animacijom + soft slide
 *   - max-width 440px (mobile-first responsive)
 *   - ESC keypress + click-outside-to-close (handler u auth.js)
 *
 * @author  Web Center
 * @version 3.6.1

   svih auth dugmadi/dropdown-a, ali NAMJERNO NE diramo `.auth-field > span`

   dekoracije koja izgleda lijepo.
