+- `onCloseMobile: () => void` - Function to close mobile sidebar
+
+### MainContainer
+Content wrapper that provides consistent spacing and optional page header.
+
+**Features:**
+- Responsive padding and margins
+- Optional page title and subtitle
+- Action button area
+- Maximum width constraint for readability
+
+**Props:**
+- `children: React.ReactNode` - Page content
+- `title?: string` - Page title (optional)
+- `subtitle?: string` - Page subtitle (optional)
+- `actions?: React.ReactNode` - Action buttons (optional)
+- `className?: string` - Additional CSS classes (optional)
+
+## Design System Integration
+
+All layout components use the established design token system:
+
+### Colors
+- Uses CSS variables from `src/styles/tokens.css`
+- Supports both light and dark themes
+- Gold accent color for branding (`--color-gold-*`)
+- Slate color palette for neutral elements
+
+### Spacing
+- Consistent spacing using design tokens (`--spacing-*`)
+- Responsive padding and margins
+- Mobile-first approach with progressive enhancement
+
+### Glassmorphism Effects
+- Backdrop blur for navigation elements
+- Semi-transparent backgrounds
+- Subtle border and shadow effects
+- Premium aesthetic for upscale venues
+
+## Accessibility Features
+
+### Keyboard Navigation
+- Tab order follows logical flow
+- Arrow key navigation in sidebar menu
+- Escape key closes mobile overlays
+- Enter/Space activates buttons and links
+
+### Screen Reader Support
+- ARIA landmarks (banner, navigation, main)
+- ARIA expanded/current states for dynamic elements
+- Skip-to-content link for keyboard users
+- Proper heading hierarchy
+
+### Focus Management
+- Visible focus indicators
+- Focus trap in mobile sidebar
+- Logical tab order
+- Custom focus styles using design tokens
+
+## Responsive Breakpoints
+
+### Mobile (< 768px)
+- Sidebar hidden by default with overlay when open
+- Header with hamburger menu
+- Stacked layout for content
+- Touch-friendly interactive elements
+
+### Tablet (768px - 1024px)
+- Sidebar overlay when open
+- Breadcrumbs visible
+- Two-column layouts where appropriate
+
+### Desktop (1024px+)
+- Persistent sidebar with collapse option
+- Full breadcrumb navigation
+- Multi-column layouts
+- Hover states for interactive elements
+
+## Usage Examples
+
+### Basic Layout
+```tsx
+function DashboardPage() {
+  return (
+    <AppLayout title="Dashboard" subtitle="Overview of your performance">
+      <div className="space-y-8">
+        {/* Your dashboard content */}
+      </div>
+    </AppLayout>
+  );
+}
+```
+
+### Layout with Actions
+```tsx
+function EventsPage() {
+  return (
+    <AppLayout 
+      title="Events" 
+      subtitle="Manage your upcoming events"
+      actions={
+        <Button variant="primary">
+          <Plus className="h-5 w-5 mr-2" />
+          Create Event
+        </Button>
+      }
+    >
+      <EventsList />
+    </AppLayout>
+  );
+}
+```
+
+### Standalone Components
+```tsx
+// Using individual components
+<div className="min-h-screen bg-gradient-to-br from-slate-50 to-slate-100">
+  <Header onToggleSidebar={toggleSidebar} sidebarCollapsed={false} />
+  <div className="flex">
+    <Sidebar 
+      collapsed={false}
+      onToggleCollapse={() => {}}
+      onCloseMobile={() => {}}
+    />
+    <main className="flex-1">
+      <MainContainer title="Custom Layout">
+        <YourContent />
+      </MainContainer>
+    </main>
+  </div>
+</div>
+```
+
+## Performance Considerations
+
+### Code Splitting
+Components use dynamic imports where appropriate to reduce initial bundle size.
+
+### Re-render Optimization
+- Uses React.memo for expensive components
+- Proper dependency arrays in useEffect hooks
+- Minimal state updates to prevent cascading re-renders
+
+### Mobile Performance
+- Touch events are optimized for responsiveness
+- Animations use CSS transforms (not layout properties)
+- Backdrop blur effects are conditionally applied
+
+## Browser Support
+
+### Modern Browsers
+- Chrome 90+
+- Firefox 88+
+- Safari 14+
+- Edge 90+
+
+### Fallbacks
+- Backdrop blur gracefully degrades
+- CSS Grid falls back to Flexbox
+- JavaScript features use polyfills where needed
+
+## Contributing
+
+When modifying layout components:
+
+1. **Maintain accessibility** - Test with keyboard and screen readers
+2. **Follow design tokens** - Use CSS variables, not hardcoded values
+3. **Test responsiveness** - Verify on mobile, tablet, and desktop
+4. **Update documentation** - Keep this README current
+5. **Performance testing** - Ensure no layout thrashing or unnecessary re-renders
+
+## Known Issues
+
+### Current Limitations
+- User authentication is mocked (displays placeholder data)
+- Navigation state is not persisted across page refreshes
+- Some animations may not perform well on low-end devices
+
+### Future Enhancements
+- Add breadcrumb customization options
+- Implement notification center in header
+- Add search functionality to header
+- Support for nested navigation menus
