Strapi already records which admin user created an entry, so the byline needs
no extra field to fill in: the Article content type sets populateCreatorFields
and the API layer exposes only that user's firstname and lastname. The name
also feeds the BlogPosting structured data.
Also fixes the gap below the article header, which until now came from the
cover image's margin and therefore vanished on articles without a cover,
leaving the body text against the byline.
Article is deliberately minimal: title, slug, Markdown body, cover image and
category. No Author content type — the administrator is the only writer.
The bootstrap hook grants the Public role find/findOne on the two content types
and disables self-registration, so the public API is read-only and the site has
no front-end accounts.
