	// Redirect base URL to mock server (This requires modifying the constant in real code,
	// but for this test script we can just verify the logic or make the URL configurable.
	// Since apiBaseURL is a constant, we cannot change it.
	// However, this test demonstrates the logic we implemented.
	// For actual running, we might need to inject the URL or make it a variable.)

	// NOTE: Since apiBaseURL is constant in standard Go we can't patch it easily without unsafe or changing code.
	// But `getDeviceDistribution` constructs the URL using `apiBaseURL`.
	// For the sake of this example, we assume we can test the parameter construction logic
	// or we would need to refactor `apiBaseURL` to be a field in `Client`.

	// Since I cannot change the constant easily to point to localhost in the compiled package
	// without refactoring, I will provide a test that *would* work if we refactored,
	// OR I can make the test just run against the real API but that requires a key.

	// Plan B: Create a test that instantiates the client and checks the URL construction if we extracted that method,
	// but we didn't.

	// Let's refactor Client to allow base URL injection for testing?
	// Or just provide a shell script for the user to run against real env provided they have keys.
	// The user asked for a "Test Script", commonly meaning a shell script to run the API.
