+ * Renders a sidebar area alongside a main content area.
+ *
+ * The sidebar area is layed out as a sticky column on large viewports.
+ * When very tall content is provided, the sidebar area will scroll vertically.
+ *
+ * The sidebar area is completely hidden on mobile viewports.
+ * Consumers should ensure that equivalent navigational elements
+ * are provided through the `mobileMenuSlot` prop.
+ *
+ * Note: this layout could _potentially_ be of use in `SidebarSidecarLayout`.
+ * For context, this layout was created after `SidebarSidecarLayout`, with the
+ * initial intent of making it easier to build a new OpenAPI docs view.
+ * It will likely make sense to consolidate somewhat duplicate layout logic between
+ * this component and `SidebarSidecarLayout`, but this did not feel like it
+ * was within the scope of the OpenAPI docs view work.
+ * Task:
