#
# What this produces (and what it cannot, on a macOS build host):
#   - a runnable portable folder: unzip → run "DoTouchAI.exe"
#   - the .exe keeps Electron's default icon (rcedit is a Windows tool we
#     cannot run on macOS); the window + tray use assets/icon.ico at runtime
#   - unsigned → SmartScreen warns on first launch ("更多信息 → 仍要运行")
#   - execution must be verified on a real Windows machine; this host cannot
#     run .exe, so the build is structural-only (files present + JS compiles)
