Disable preview when Canvas is enabled
The Disable preview when Canvas is enabled ECA workflow turns off the built-in content preview for a content type once that type uses Drupal Canvas for its full display, because Canvas provides its own live preview.
This model is provided by the Drupal CMS Content Type Base recipe (drupal_cms_content_type_base). The screenshot below shows the model open in the Workflow Modeler.

How It Works
Event, Content template created: Fires when a Drupal Canvas content template (canvas.content_template.node.*) is saved.
Conditions: The workflow continues only when both are true, combined with an and step:
Template enabled?: The saved template is turned on.
Template targets full view mode?: The template is for the content type's full display.
Action, Disable preview for content type: Temporarily switches to the administrator account and sets the content type's preview mode to off.
The effect is that content types managed with Drupal Canvas no longer show the standard "Preview" button, avoiding a second, redundant preview.
Viewing the Model
Go to Administration \ Configuration \ Workflow \ ECA, find Disable preview when Canvas is enabled, and open it in the Workflow Modeler.
