| 2 | +LingoDotDevEngine wraps the Lingo.dev localization API for PHP consumers. |
| 3 | + |
| 4 | +Use a single engine instance to translate strings, arrays, and chat logs, or |
| 5 | +to detect the locale of free-form text. The engine handles request batching, |
| 6 | +progress reporting, and surfacing validation or transport errors. |
