.SYNOPSIS
  Start the Windows Sandbox smoke test of dist\flash-card.exe from the host.

.DESCRIPTION
  Writes a configuration from flash-card.wsb with absolute paths, starts
  Windows Sandbox, waits for out\result.json and prints the summary.
  The tests themselves (window, click, progress file) run inside the sandbox
  with the sandbox's own mouse; the host's mouse and focus are not used.
  Windows Sandbox shows its own window while it runs. Needs Windows 11 Pro
  with the feature "Windows Sandbox" enabled.

.EXAMPLE
  powershell -File tools\sandbox\run.ps1 -Runs 5
#>
param(
    [int]$Runs = 5,
    [int]$TimeoutMinutes = 15
)
