What
The workshop skill no longer picks between HTML and markdown per document. Every workshop is written as a .workshop.html page. The markdown lane survives only for a document that the session's own plan-mode instructions already designated as .workshop.md. If you ask for markdown, Claude will say the workshop page is authored as HTML and use an .html path instead.
