How do I feature an episode inside an article or page?

Add the Episode Link block, in the Podspun Dataweaver: Podcasts section of the block picker. Start typing an episode title and pick it from the list: the block shows that episode's image, big, with a play badge and a "Watch the Episode" label, linked to the episode's page on your site. You can change the label in the block's settings.

Articles written from an episode (the Write From an Episode button and auto-drafts) include this block automatically, so every generated article features the episode it came from.
