+`getToken()` now throws `ClerkOfflineError` instead of returning `null` when the client is offline.
+
+This makes it explicit that a token fetch failure was due to network conditions, not authentication state. Previously, returning `null` could be misinterpreted as "user is signed out," potentially causing the cached token to be cleared.
+
+To handle this change, catch `ClerkOfflineError` from `getToken()` calls:
+
+```typescript
+import { ClerkOfflineError } from '@clerk/react/errors';
+
+try {
+  const token = await session.getToken();
+} catch (error) {
+  if (ClerkOfflineError.is(error)) {
+    // Handle offline scenario - show offline UI, retry later, etc.
+  }
+  throw error;
+}
+```
