 * @remarks
 * Battery-scoped exception classes for the model-less, shell-out OS-native text-to-speech adapter
 * (macOS `say` / Linux `espeak-ng` / Windows PowerShell `System.Speech`), minted via `createException`
 * from `@nhtio/adk/factories`. Two categories are fatal config/contract bugs (invalid options,
 * unsupported platform — both 529); two are non-fatal runtime failures (engine error 502, timeout
 * 504) so a caller may retry with a different voice/rate or fall back to another TTS engine.
 */

 * Thrown when the resolved adapter options fail validation against
 * {@link @nhtio/adk/batteries/tts/native!nativeTtsOptionsSchema} — e.g. an unknown option key, a
 * non-numeric `rate`, or a `platform` outside the supported set. Fatal: config bugs fail loud, not
 * at `synthesize` time. Printf arg: `[detail]`.
