When using the edit-site editor, there will be many blocks that are "tokens" for content that is going to be loaded dynamically. This includes blocks like post-title, post-content, post-date, and so on, since there is no specific post to show when in template editing mode. The clarity of this design — which is different to the placeholders shown in content blocks like images or cover — is crucial to understand when you are editing a template and when a specific page. This needs a few design explorations to see how close or how different it should be from current block placeholders.
