This post is credited to two people. Its byline names both, each linking to an author page listing what they wrote, and the card at the foot carries the fuller version with headlines and links.
Authors come from data/authors/, one file per person, keyed by filename. A post lists
the keys it wants in authors, and a key with no matching file fails the build rather
than quietly dropping somebody’s name from their own work.
A post that says nothing about authors falls back to the single [params.author] in
site config, which is what every other post on this site does.
