// internal/audio is created with Manager, TTSProvider, and the 4 Register*
// functions. Once compile passes, tests exercise the minimum surface needed
// by phase-01 callers (NewManager, RegisterTTS, HasProviders, zero-value
// chains).

// NOTE: stubTTS.Synthesize takes `any` for ctx to avoid importing context in
// the smoke test — the TTSProvider interface will enforce context.Context via
// compile check when we add `var _ audio.TTSProvider = stubTTS{}`.
//
// Smoke test intentionally omits the `var _ audio.TTSProvider = stubTTS{}`
// assertion because stubTTS uses `any` for ctx. Provider-interface conformance
// is covered by the alias_test (tts.Provider alias of audio.TTSProvider) and
// by production provider packages (elevenlabs, openai, edge, minimax).
