Thumbnail attachment on publish sits behind a remote flag defaulting false.
Publishing a plain page can now scan it for declared thumbnail tags and attach a light and a dark thumbnail alongside the page. The whole path sits behind the remote config flag tengu_cobalt_plinth_campion, which defaults to false in this build, so no publish attaches thumbnails unless the server turns it on.
- Applies only to plain pages, not typed artifacts or live docs.
- Sends
thumbnailandthumbnailDarkfields with the publish call. - Thumbnails that cannot be read are reported back as publish warnings rather than failing the publish.
- Resolved thumbnail links are tracked in a per-publish cache.
