Track download progress in layaService (bytes/total, phase, error state) and expose it through the laya status route. Render a progress bar during model download in Settings via a layaStatusPresentation service, and display download/status errors inline instead of failing silently. Cover progress tracking and status presentation with tests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
