A self-contained console-interaction demo.  

Run with all interaction-related operational switches set to False (or 0) in 
configs: no fixer-script offer, pre-step pauses, or proxy-sync verifies are run.  
In this mode, the only points where input is required are when verifying removal
of existing content on the PC (not shown here), and prompting for manual copies 
of zipfiles on the phone.  PC commands were run in Terminal (on macOS), and phone 
commands in Termux (on Android 11).
