Snippet and block preview dialogs create small render jobs. They are meant for fast checks before a larger manuscript or book render.
- Text or selected block content is the render source.
- Voice and format controls affect the preview output when the dialog exposes them.
- Play becomes useful after the render job succeeds and an audio artifact is available.
- Download saves the available artifact from the completed job.
If a small preview fails, fix that failure before starting a larger render.
