At the bottom of this post is a two-column layout showing two versions of the
meteors spinner. I broke that in a previous commit and this commit brings it back.
Use the new content-grid shortcode (implemented in the submodule commit) to render
a two-column grid.
- Add descriptions for pages that have too much content
- Add an image orientation override param so that I can specify orientation when it's missing from EXIF
- Move the author.name and author.email configurations to params; delete author.yaml
