+  This layout renders its own <router-view/> rather than a <slot/>, so the
+  keep-alive/suspense wrapper App.vue builds around its own <router-view> never
+  reaches these routes. The keep-alive below is the one that applies: the main
+  tabs stay mounted between switches instead of refetching on every visit.
