 Better organization of CSS media queries
 Added proper touch device detection
 All changes maintain existing functionality while improving user experience, accessibility, and performance. The mobile menu now behaves more naturally, with proper closing behavior and smooth transitions.

+
+Current Implementation Analysis:
+
+Theme System Architecture
+CSS Variables (variables.css): ✓ Well-structured light/dark theme variables ✓ Logical separation of common tokens ✓ Clear naming conventions ✓ Efficient use of CSS custom properties
+Theme Switching (theme.js):
+Robust Implementation: ✓ IIFE for encapsulation ✓ Early initialization prevents FOUC ✓ System theme preference detection ✓ Local storage persistence ✓ Comprehensive error handling
+CSS Structure:
+Modular Organization: ✓ Separate files for different concerns ✓ Clean inheritance patterns ✓ Proper cascade management ✓ Efficient variable usage
+Integration:
+Clean Component Integration: ✓ Theme toggle properly placed in header ✓ Smooth transitions between themes ✓ Proper script/style loading order
+Strengths to Preserve:
+
+The modular CSS architecture
+The CSS variables-based theming approach
+The early theme initialization
+The system preference detection
+Minor Optimization Suggestions:
+
+Theme Switching Performance:
+
+/* Add to variables.css */
+:root {
+  /* Add GPU acceleration for theme transitions */
+  --theme-transition: color var(--transition-speed) ease,
+                     background-color var(--transition-speed) ease;
+  --gpu-accelerated: translate3d(0, 0, 0);
+}
+Theme Toggle Accessibility:
+
+/* Add to header.css */
+.theme-toggle:focus-visible {
+  outline: 2px solid var(--primary);
+  outline-offset: 2px;
+  border-radius: var(--border-radius);
+}
+Theme Persistence Enhancement:
+
+// Add to theme.js persistTheme function
+function persistTheme() {
+  try {
+      const currentTheme = getCurrentTheme();
+      localStorage.setItem(THEME_STORAGE_KEY, currentTheme);
+      // Add theme to body for better SSR support
+      document.body.dataset.theme = currentTheme;
+  } catch (error) {
+      console.warn('Theme persistence error:', error);
+  }
+}
+These suggestions maintain the existing architecture while adding:
+
+Improved performance through GPU acceleration
+Enhanced accessibility
+Better server-side rendering support
+The current implementation is well-structured and follows best practices. The suggested optimizations are minimal and non-invasive, preserving the existing functionality while making subtle improvements to performance and accessibility.
