Great! I can see there's already a sidebar component in the project. Let me check the existing sidebar to understand the current implementation:

I can see the existing sidebar infrastructure. Now I'll create a production-ready sidebar navigation component with all the features specified. Based on the design inspiration showing modern SaaS dashboards, I'll build a clean, professional sidebar with proper responsive behavior.

Let me create the complete sidebar implementation:

Now let me update the layout to properly wrap the app with the sidebar provider and add the correct background styling:

I've created a complete, production-ready sidebar navigation component with all the features you requested:

What I Built

Sidebar Features:

• Logo section at the top with branding and version
• Vertical navigation menu with 5 sample items (Dashboard, Projects, Analytics, Messages, Settings) each with icons
• Active state styling - clear visual indicator for the current page
• Smooth hover effects and transitions
• User profile section at the bottom with avatar, name, email, and a dropdown menu

• Responsive behavior:

  • Desktop: Full sidebar visible with icons and labels
  • Tablet: Icon-only collapse mode (use Ctrl+B or Cmd+B to toggle)
  • Mobile: Slide-out drawer activated via the hamburger menu button

Design & Polish:

• Uses your existing design system tokens (sidebar colors, borders, spacing)
• Clean monochrome color scheme with subtle accents
• Proper semantic HTML and accessibility features
• Icons from Lucide React for consistency
• Avatar component for user profile
• Dropdown menu for additional actions

The sidebar is fully integrated with the existing SidebarProvider component infrastructure in your project, supporting all variants (sidebar, floating, inset) and collapsible states. The example page demonstrates all interactions and includes sample content to show how it works with your main content area.
