Initial Assessment

app-marketing-context.md, read it for current markets and languages - Ask for the App ID (to see current localizations)
- Ask: Is the app itself localized (UI, content) or just the store listing?
- Ask: Which markets are they considering?
- Ask: Budget, professional translation or AI-assisted?
