I see there's already a theme-provider.tsx and next-themes in the project. Let me also check the existing theme provider and existing images:

Good. The previous images seem to have been deleted. I need to generate new images for the navigation website categories. Let me now plan the full navigation site and generate all the images needed. I'll create categories like AI tools, developer tools, design resources, cloud services, etc., with multiple sites per category. Let me generate representative images for each site and then build the components.

Now let me generate the remaining images for the last category:

All images generated. Now let me update the globals.css with light/dark theme tokens:

Now let me update the layout to include the ThemeProvider:

Now let me build the core components. First, the navigation data:

The autofix broke the import. Let me fix it:

Now let me create the 3D tilt card component for the nav site:

Now create the sidebar component:

Now create the main content area with category sections:

Now create the main page component that ties everything together:

Now update the main page.tsx to use the new NavPage:

Let me verify all the key files are correct:

All components look correct. Let me also fix the h-4.5 w-4.5 class in the content area since Tailwind doesn't have that by default -- let me use h-[18px] w-[18px] or the standard h-5 w-5:

The navigation website is now complete. It features a fixed left sidebar with 6 categories (AI tools, developer tools, design resources, cloud services, productivity tools, community resources) containing 24 sites total. Each card uses the 3D tilt effect that follows the mouse cursor with a radial light glare, smooth hover scaling, and staggered entrance animations. The sidebar highlights the active category as you scroll, clicking a category smoothly scrolls to its anchor section, and the theme toggle in the sidebar footer switches between light and dark modes using next-themes. The entire UI is in Chinese with responsive mobile support via a slide-out drawer.
