- Sticky top nav bar replacing TotalsBar with full navigation
- Logo, Home/Collection/Setups links, search bar, and user avatar
- NavLinkOrButton helper: button for anon users on protected routes, Link for authenticated
- Active route highlighting via useMatchRoute
- Desktop search bar triggers openCatalogSearch('collection')
- Desktop nav links hidden on mobile (hidden md:flex)
- Uses LucideIcon wrapper, not direct lucide-react imports
[Rule 1 - Bug] Used 'house' icon fallback check: plan specified 'home' which does not exist in lucide-react; 'search' and 'layers' verified present
