A first visit now follows the device language when no site language is saved.
When the browser has no saved Ronova site-language choice, the public website now checks the browser and operating-system language list and opens the matching English, German, French, Japanese, or Traditional Chinese route.
- A language selected from the site, or an explicitly opened localized route, is remembered and takes priority over later environment detection.
- Unsupported languages stay on English, Simplified Chinese is not mislabeled as Traditional Chinese, and no additional identity or account state is created.
