📝 Notes

draw.io uses the Electron/NSIS user-level install pattern — no HKLM writes.
Diagram files (.drawio, .xml) are opened directly without file association registration.
All application preferences are stored in %APPDATA%\draw.io\ as JSON.
The desktop app can open .drawio and .xml files via the drawio:// URI scheme.
