// Package elevenlabs provides a Go client for the ElevenLabs TTS API.
//
// ElevenLabs is a text-to-speech API that generates high-quality, natural-sounding
// voices for applications including voiceovers, podcasts, and video content.
//
// Basic usage:
//
//	client, err := elevenlabs.NewClient(elevenlabs.Config{
//	    APIKey: os.Getenv("ELEVENLABS_API_KEY"),
//	})
//	if err != nil {
//	    log.Fatal(err)
//	}
//
//	// Generate speech audio
//	audio, err := client.TextToSpeech(ctx, "voice-id", elevenlabs.TextToSpeechRequest{
//	    Text: "Hello world",
//	})
//	if err != nil {
//	    log.Fatal(err)
//	}
//
//	// audio is []byte containing MP3 data
//
// The client automatically handles retries for server errors (5xx) and rate
// limits (429) with exponential backoff. Use the sentinel errors (ErrRateLimit,
// ErrServerError, etc.) with errors.Is() for programmatic error handling.
