rem Build the ZUPT GUI installer without downloading dependencies.

rem Prerequisites must already be installed: Python 3.9+, PySide6, PyInstaller,
rem Inno Setup 6, and a source-built/tested zupt.exe. The CLI path can be
rem selected with ZUPT_CLI_EXE. Final output goes to ZUPT_DIST_DIR,
rem which defaults to a directory below %%TEMP%% (outside the Git checkout).
rem ZUPT_WINDOWS_RUNTIME_NOTICES_DIR is mandatory and must contain the
rem license/notices for the exact Python, PyInstaller, Qt and PySide/PyQt
rem runtime files embedded by this local build.
