rem  SMSBlaster - one-click phone installer for Windows (hosted tenants).
rem
rem  This sideloads the SMSBlaster Android app onto a USB-connected phone. It is
rem  a standalone replacement for the desktop app's built-in installer, for
rem  customers who use the hosted web edition and have no Electron app.
rem
rem  Pairing is NOT done here: after the app installs, the operator pairs the
rem  phone from the website (Devices -> Pair a phone -> scan the QR).
rem
rem  Requires Windows 10 1803+ (ships curl.exe and tar.exe in System32). No
rem  admin rights and no separate "install adb" step: Google's platform-tools
rem  are downloaded into %TEMP% on first run. https://app.smsblaster.verilexdata.com is substituted by
rem  the server when it serves this file, so the APK comes from the same server.
