Eliminate the flashbangs

[Geordanny1]

I don't like when I change from page to change in dark, the page changes to white for a few seconds.

And a found a way to fix it and it is by adding lines of code

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

Where would be a nice to put them?

What do you mean by the page changes to white for a couple seconds? I mostly use Chrome for development - with others for testing - and with the latest version of the template it's pretty much an instantaneous change.
