+# OPTIONAL Frappe Drive integration: register a Draw diagram as a Drive file so it
+# shows up in the user's Drive, like a Sheets/Slides/Writer doc. Deliberately
+# soft-coupled — Draw does NOT list Drive in required_apps, so it stays installable
+# standalone (e.g. on Frappe Cloud without Drive). Every entry point no-ops cleanly
+# when Drive is absent or not yet set up (no team).
+#
+# A diagram is registered as a Drive "native document" File: a File row with
+# content_doctype="Draw Diagram" + content_docname=<name> (Drive's own pattern for
+# app-owned docs). Rendering the diagram INSIDE Drive needs a Drive-side viewer for
+# this content type (a Drive change), which is out of scope here.
