(If you are running this app on device, turn it upside down to see 'palm-dark' styling in action.)
By default, Mojo's widgets are styled to support scenes with dark text on a light background. For dark scenes (light text on a dark background) Mojo provides an alternate set of dark styles.
To apply this theme to your scene, add the 'palm-dark'
class to your body or top-level scene element.
