   43. DARK MODE TOGGLE - JavaScript Snippet
   ============================================================
   Include this script in base.html <head> (before body renders)
   to prevent flash of wrong theme:

   <script>
   (function() {
     var theme = localStorage.getItem('theme');
     if (theme === 'dark' || theme === 'light') {
       document.documentElement.setAttribute('data-theme', theme);
     } else if (window.matchMedia('(prefers-color-scheme: dark)').matches) {
       document.documentElement.setAttribute('data-theme', 'dark');
     } else {
       document.documentElement.setAttribute('data-theme', 'light');
     }
   })();
   </script>

   Then for the toggle button (in navigation):

   <button class="theme-toggle" onclick="toggleTheme()" aria-label="Toggle dark mode">
     <svg class="icon-moon size-5" ...><!-- moon icon --></svg>
     <svg class="icon-sun size-5" ...><!-- sun icon --></svg>
   </button>

   <script>
   function toggleTheme() {
     var current = document.documentElement.getAttribute('data-theme');
     var next = current === 'dark' ? 'light' : 'dark';
     document.documentElement.setAttribute('data-theme', next);
     localStorage.setItem('theme', next);
   }
   </script>
