Sets or clears the default idle content for a display. Idle content is shown whenever the display has no active live content. Provide html OR url to set idle content (mutually exclusive — url is wrapped in a full-page iframe document), or omit both to clear idle content. Provide content_description to make later state reads easier for agents. When the display is currently idle (no active live content), the new idle is pushed to the display immediately; otherwise it stays dormant until the live content ends. Requires admin scope.
