The ThemeToggle component was causing hydration errors because the server and client rendered different icons (Sun/Moon) based on the theme state. Changes: - Render a placeholder button until component is mounted - Only render the actual theme icon after client-side hydration - This ensures server and client HTML match during initial render Fixes console error: 'Expected server HTML to contain a matching <circle> in <svg>'
