Using https://docs.cartesia.ai, complete the following task:

Using Cartesia, build me a Python script that converts text to speech:

1. Follow the Cartesia documentation to authenticate and choose the simplest text-to-speech API path
2. Convert this text to speech:
   "Your order has been shipped and will arrive by Friday."
3. Save the audio as output.mp3. If only WAV output is supported, save it as output.wav instead
4. Print a confirmation message with the filename when the file is saved

Use documented Cartesia APIs only; do not generate fake or placeholder audio.
