+ * NOTE
+ * The ./unread.ts API:
+ *
+ * - Provides a `checkUnread()` function to sync with the server,
+ * - Periodically calls `checkUnread()`, and
+ * - Caches the first page of notifications.
+ *
+ * IMPORTANT: This query uses ./unread.ts's cache as its first page,
+ * IMPORTANT: which means the cache-freshness of this query is driven by the unread API.
+ *
+ * Follow these rules:
+ *
+ * 1. Call `checkUnread()` if you want to fetch latest in the background.
+ * 2. Call `checkUnread({invalidate: true})` if you want latest to sync into this query's results immediately.
+ * 3. Don't call this query's `refetch()` if you're trying to sync latest; call `checkUnread()` instead.
