In the current scope of the feature, only a single master brand book can be configured and used across an entire workspace. By default, this master configuration applies across all teams. The ability to create multiple independent brand book and assign access permissions to specific teams within a single workspace is planned for a future release.

Automatic ingestion relies on background crawling scripts. If your website incorporates strict cross-origin resource sharing (CORS) rules, access restrictions, or web application firewalls, the background scanner is blocked from accessing those assets. Logos hosted behind authentication or fonts loaded from private CDNs are also often skipped. In these cases, use the manual workflow to update your brand book assets.

Publishing modifications to your brand book immediately updates the default options available inside the asset color pickers and typography menus for new campaigns. However, existing live experiences and pre-saved campaign templates do not update their styled layouts automatically. Changes to existing editor elements must be managed manually within the visual editor interface.
