// Package tts is a thin backward-compat alias over internal/audio.
//
// The real implementation lives in internal/audio (TTS + STT + Music + SFX
// unified manager). This file preserves the legacy 24-symbol surface so that
// pre-Phase-1 callers continue to compile unchanged. New code should import
// internal/audio directly — the aliases here will be removed after all
// callers migrate.
//
// Contract: every exported symbol that existed in the pre-Phase-1 tts package
// has an alias or constructor below. If you add a new exported symbol to
// internal/audio that previously lived in tts, also add it here — and to the
// alias_test.go symbol-coverage test.
