New design from prototype: fixed 60px sidebar (logo, vertical gold line, hamburger, social icons, lang switcher) replaces the horizontal header. Overlay is a 3-column fullscreen menu on desktop (main nav left, subnav middle with hover panels, utilities right with close/logo/CTAs) and a single-column accordion menu on mobile. Content shifts paddingLeft:60 to clear the sidebar on all screen sizes. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
