theme switcher on demo, takes 2 click initially.

Thanks for reporting this.

The issue was due to the currentTheme variable not being initialized when the system preference is used to set the theme at the start of the page load. Thus, when the theme switcher was first clicked, it didn't work as expected because currentTheme was null instead of being either 'dark' or 'light'.

I've corrected this by ensuring the currentTheme variable is properly initialized based on the system preference if there's no saved theme in localStorage. The theme switcher should now work correctly on the first click, regardless of your system's color scheme preference.
