• Language: public language code, ISO-639-1 where available and ISO-639-3 otherwise.
• Confidence: probability for the top language prediction.
• Predictions: ranked language candidates with ISO codes and raw scores.
• Constraints: optional expected_languages restrict predictions to likely language codes.
