+    installation metadata, database or server processes. Only Overview and application Settings appear in the sidebar.

   * **Open points:** ask the launcher maintainers before putting heavy load on their API; DBCs live inside the MPQ patch archives
     (extracting them would need an MPQ reader), so the server's `Data\dbc` still comes from our `base` package for now.
