   Syntax highlighting for markdown code blocks.

   commonmarker (comrak) renders fenced code with the syntect highlighter in

   MarkdownHelper. It emits <pre class="syntax-highlighting"> and wraps tokens in
   spans whose classes are TextMate scope names (e.g. "keyword control def
   ruby"). We colour the broad scopes with the same --nv-syntax-* tokens the
   CodeMirror theme uses, so chat code matches the editor. Space-separated scopes
   compound on one element, so `.entity.name.function` requires all three classes
   present. Vocabulary: TextMate/Sublime scope naming conventions. (The <pre> box
