// [ZASO] Notification Banner
//
// Every variable SiteOrigin injects from get_less_variables() must ALSO be
// declared here with a `default` placeholder, exactly as the Alert Box does.
// Referencing an injected variable that is not declared in this file makes the
// LESS fail to parse and SiteOrigin silently emits ZERO bytes of CSS, shipping
// the widget completely unstyled.
//
// Selectors are scoped and doubled where a theme is likely to fight us (themes
// paint every `button` and every `a` inside content). Higher specificity is used
// instead of !important, per the plugin coding standard.
