+// FIXME: React Query caching issues with cross-tab synchronization
+//
+// The default React Query behavior caches data indefinitely until invalidated,
+// which should work well in theory. However, we're experiencing two problems:
+//
+// 1. Navigation between pages doesn't refresh data as expected by users
+// 2. Query invalidation doesn't work properly across browser tabs - changes
+//    made in one tab (like updating room settings or deleting transcripts)
+//    aren't reflected when navigating in another tab without a full page refresh
+//
+// As a temporary workaround, we're setting a short staleTime to force data
+// reloading, similar to our previous implementation. This should be revisited
+// once we can resolve the underlying invalidation and cross-tab sync issues.
+// 500ms is arbitrary.
