/* ============================================================
   Novi kolesarski — site.css
   Shared design tokens, base styles, and reusable components.
   Source of truth: design-system.html (April 2026, v1.0).
   Extracted from the 11 mockups during Session 2 (27.5.2026).

   What lives here:
     - :root tokens (identical across all 11 mockups)
     - Resets + base typography
     - .wrap (max-width container)
     - .nav block (sticky nav, logo, links, language dropdown)
     - .btn family (.btn, .btn.ghost, .btn.light, hover, arrow)
     - .sec-head / section rhythm defaults (104px desktop, 64px mobile)
     - .cta dark band + .cta-form + .cta-photo (used on 5 pages)
     - footer block (identical on all 10 footered pages)
     - One shared responsive break at 880px (matches design-system.html)

   What stays inline per mockup:
     - .hero (homepage full-bleed)
     - .page-hero (light vs dark variants per page)
     - Page-specific content sections (.story, .entity, .legal, ...)
     - Mockup-specific responsive overrides
