1. Right panel: Explains in parent's native language what this
exercise is about and how it works (TR/AR/UK/RU/PL translations)
2. Trilingual buttons: "Dogru" (primary) with "Richtig / Correct"
subtitle so parents understand even if language detection is wrong
3. Native word shown prominently: "= elma" next to "apple"
4. Audio buttons labeled EN/DE/TR with language codes
5. Answer card shows all 3 languages: English, Deutsch, native
6. Progress tracker in the explanation panel
