Hmmm...the image is working now (https://github.com/flosse/cobalt-issue-557/commit/5d265ff785398df2b941502a3111f792f052a744) but the excerpt does not:

I noticed that in the error, the post does not include excerpt.

Since I haven't touched this part in a while, I had to dig in further. Apparently, content and excerpt are only available for your own page during the processing of posts. Once we start processing non-post pages, we make these variables available.

I'm assuming the intent is for creating a menu. We'd need to split layout rendering into a separate pass from content/excerpt. This seems like a reasonable request until / if we get support for proper menu generation.

We'll probably want to do #560 first.
