Dark mode toggle for Cecil

This website is the demo of the Dark mode toggle component theme for Cecil.

Click the moon (or the sun) in the header, or the big button below, to switch between the light and dark color schemes:

• your choice is remembered, until it matches your system preference again;
• change the color scheme of your system: the page follows it;
• reload the page: there is no flash of the wrong color scheme.

The big button is the same partial, customized with CSS custom properties, and the buttons below use the JavaScript API (window.colorScheme.set()).
