Theme Toggle
Renders the theme switch button used by the navbar. It cycles through the supported theme preferences and stores the selection in localStorage.
{% include components/theme-toggle.html %}
Example
The default layout includes the toggle as part of the navbar. It can also be included separately in a custom layout. No parameters are required.
Supported preferences are light, dark, and system. The button has an accessible label and is enhanced by assets/js/components/theme.js.
