 <p class="demo-description">
 When persisted state contains incomplete uploads from a previous tab
 session, the uploader now shows a confirm modal: <strong>Resume all</strong> or
 <strong>Discard</strong>. Resume re-adds the tasks to the queue and
 automatically starts uploading (when <code>persistBlobs</code> kept the
 File data). Discard clears the persisted store. Set
 <code>restorePrompt: false</code> for the legacy auto-rehydrate
 behaviour, or pass a function for a custom UI.

 <strong>Try it:</strong> queue a large file, click Start, then reload the page (F5) before it finishes.
 On reload you'll see a modal: Resume all (auto-rehydrates + restarts) or Discard (clears IndexedDB).
