+/**
+ * Under zh-CN, the Task Detail page's "Awaiting review" banner
+ * (`record:alert`, shown while a task is in review) is served in Chinese
+ * like the rest of the page.
+ *
+ * The banner's two strings travel by two routes. `title` is translated by the
+ * bundle through the page-component route
+ * (`pages.showcase_task_detail.components.review_alert.title`), which needs
+ * the node's `id` — before it had one the route could not address it and the
+ * title stayed English. `body` has no key on that face, so it is an inline
+ * locale map on the page; the renderer picks the reader's locale from it
+ * (`pickLocalized`), so the served document must still carry that map
+ * intact. The pin is the translator applied to the page with the app's own
+ * bundle, which is what the REST boundary does per request locale.
