   Layout strategy: on the guide page, body is a flex row. The page content
   sits in .page-shell (flex: 1) and the drawer is a sibling flex item that
   expands from 0 to 480px when open. This guarantees the drawer can NEVER
   overlap content because they live in the same flex layout.
   On narrow screens we fall back to the classic overlay behavior. */
