AI translates the explanation and quiz text while preserving code and answer scoring.

Job chaining runs jobs sequentially, stopping the chain if one fails, using Bus::chain([...])->dispatch(). Job batching (Bus::batch([...])) runs jobs in parallel while tracking overall progress, exposing then(), catch(), and finally() callbacks for handling completion or failures. Batches are useful for bulk operations like processing thousands of blockchain transactions or sending mass notifications.
