Switching from DeepL to Argos Translate

`pip install argostranslate`. In Python: `import argostranslate.package, argostranslate.translate; argostranslate.package.update_package_index(); pkg = next(p for p in argostranslate.package.get_available_packages() if p.from_code=='en' and p.to_code=='de'); argostranslate.package.install_from_path(pkg.download()); print(argostranslate.translate.translate('Hello world', 'en', 'de'))`. Argos is the engine LibreTranslate wraps — pull it in directly for offline / scripted translation pipelines.

Good fit for: Batch translation pipelines (subtitle files, document translation jobs) where you don't need an HTTP service.
Weak at: No HTTP API by default; you build the service layer if you need one (or use LibreTranslate).
