// Full width layout. Ported from the Discourse Full Width theme component here
// https://meta.discourse.org/t/discourse-full-width-component/292496, which we
// intend to move into core over time.
//
// We are copying this here so we can continue to iterate on Horizon with full
// width without having to include the theme component as a dependency, we
// need to remove this once full width is in core.
