Local Run

1. Open chrome://extensions
2. Enable Developer mode
3. Click Load unpacked
4. Select this folder: Translator-extension

Usage

1. Select text on any page, right-click, then choose Translate selected text.
2. Choose Translate to Chinese (中文) or Translate to English.
3. An inline bubble appears near selection and shows translation result.
4. Click Copy in the bubble to copy translated text.
5. Click extension icon to open side panel for full translator controls.
6. First run may download required resources; after that it can work offline for cached language pairs.

Offline Notes

• Offline translation is language-pair specific.
• Keep network connected for the first successful translation of each pair (for example en -> ja) so Chrome can cache that pack.
• If offline and a pair is not cached yet, the UI now shows a clear error asking you to pre-download online once.
