YAML multiline string literals are not parsed properly from frontmatter

After going through the workflow in which I got to wondering about #14, I finally got records published and test comments: https://heaths.dev/atproto/2026/02/21/publishing-to-the-atmosphere.html. Everything seems to be working, except...

One thing I found possibly wrong in the workflow is that if I publish first and post is created on Bluesky, it's not yet published so the post has no thumbnail rendering. Just a > for content: https://bsky.app/profile/heaths.dev/post/3mfdr2altlh2w

Seems the post needs to be up first, or should an abstract be published instead?
