Every time the event specified in the hook happens inside the design system, your exporter will run. The following types of events can be watched for in the design system:
The exporter will run every time a new version of a design system is released.
Supernova will run the exporter every time anything changes in your design system, with a short buffer window so you don't get overwhelmed with updates.
The exporter will run every time the source is updated and there is new data — for example, if a Figma file is published.
