+"""Tests for the frozen-exe build script + frozen-aware config default.
+
+The PyInstaller run itself is Windows-only and slow; these tests cover the
+pure logic the build script and the CLI rely on. The build script is
+PowerShell (``scripts/build_exe.ps1``); the tests assert on its content and
+on the CLI behaviors the produced exe depends on.
