  Author Card — renders at the bottom of any post.

  USAGE: Add to the bottom of any post file:
    {% include author-card.html %}

  In the post's front matter, set one of:
    author: gingerpersolus       → full card (photo + bio) from _data/authors.yml
    author: "Sam Reich"          → name-only card (person not in data file)

  Leave "author:" out entirely to show no card at all.
