+ *               NATIVE trash button on the shared PortalActivity WebView, shown only while the
+ *               /kiwix/ page is loaded. Tapping it opens a ~45% bottom sheet (title + search + the

+ *               a pinned "Get more content" button to the Wikipedia & ZIM screen) backed by the REST
+ *               endpoints (KiwixClient GET /kiwix/library, POST /kiwix/delete). After a delete the
