prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Enable Adobe DTM for Analytics (closes #160)
  This embeds the code but Adobe’s instructions violate web
  performance guidelines and we should review this carefully
  to see how much Adobe is affecting site performance.
  
  --- END ISSUE ---
