  Category names are already written in display case in front matter
  ("Agentic-AI", "Retrieval-Augmented-Generation"), so replacing the separators
  is the whole job — which is what index.html and _layouts/post.html do. Not
  `capitalize`: it lowercases everything after the first letter, so "Agentic-AI"
  would render as "Agentic Ai".

  `listed` drops a translation whose original is listed (_plugins/translations.rb).
  The divider goes before each group after the first, so a category left empty by
  the filter leaves no stray line behind.
