+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.
