# load one of the built-in themes
# load an external theme
# add additional styles

These options should be documented in the theme’s documentation.
--theme-style <path> to override any variable, and make the theme your own!
// Overriding theme variables is an easy way to customize a theme.

@theme-variable: 'new value';
// You can also override any other elements.
// Your styles will be applied on top of the existing theme styles.
// However the name of CSS classes or IDs might change with new theme versions.
