+- **`Scripts/Start-IntuneToolkit.ps1`**
+  - Added menu entries for baseline deployment:
+    - `10. Deploy baseline`
+    - `11. Deploy baseline (dry-run / WhatIf)`
+  - Forwards `-WhatIf` switch correctly when dry-run option is selected.
+  - Ensures `WhatIf` flag is cleared between loop iterations to avoid leakage to other tools.
