  * Why do we need a wrapper component?
  * 
  * Astro passes `children` as a string of HTML, so we need
  * a way to render that content.
  * 
  * Rather than passing a magical prop which needs special 
  * handling, using this wrapper allows Svelte users to just
  * use `<slot />` like they would for any other component.
