✅ Translation Guidelines
DO:

✅ Use Hindi translations ([app_localizations_hi.dart](vscode-file://vscode-app/c:/Users/miet/AppData/Local/Programs/Microsoft%20VS%20Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)) as reference
✅ Maintain consistent terminology across strings
✅ Test translations in actual app UI
✅ Keep technical terms unchanged (MB, GB, "Whisper")
DON'T:

❌ Use Google Translate blindly
❌ Translate brand names ("Resonate")
❌ Modify string keys or function names
🎯 Acceptance Criteria
All strings from [untranslated.txt](vscode-file://vscode-app/c:/Users/miet/AppData/Local/Programs/Microsoft%20VS%20Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) translated for target language
App UI displays correctly (no overflow, proper alignment)
