## Title

    [huggingface_hub] OfflineModeIsEnabled "Cannot reach https://huggingface.co/api/...: offline mode is enabled. To disable it, please unset the `HF_HUB_OFFLINE` environment variable."

## Body

    Cause (Documented platform behavior): In offline mode every outgoing Hub request is blocked by an event hook that raises OfflineModeIsEnabled (a ConnectionError subclass); only cache-aware download helpers can fall back to local files.
    
    Fix status: documented_behavior
