 AutoCast now ships with an optional [Weights & Biases](https://wandb.ai/) integration that is
 fully driven by the Hydra config under `configs/logging/wandb.yaml`.

+- Enable logging for CLI workflows by passing Hydra config overrides as positional arguments:

 - The autoencoder/processor training CLIs pass the configured `WandbLogger` directly into Lightning so that metrics, checkpoints, and artifacts are synchronized automatically.
