I'm a beginner in this area, and I have a question. In YouTube tutorials, connecting via the WordPress REST API or other external CMS (Data Variables) is usually done in the BODY. Does it have to be this way, or can the data source be added, for example, in a section of the page? Does this affect performance?

I connected the Test page via REST as a test. The blog subpage displays the post content, but the image within the content is missing. In the page's code, the image source link is visible and correct. What am I doing wrong? https://00-blueprint-5pqx0.wstd.io/blog/stress-free-compliance-and-controls

Can the domain be configured on the Webstudio side so that the website is published to a subdirectory like domain.com/blog instead of domain.com?
