Phase 1.1 — user_language_api.py: Stores native language preference per user (TR/AR/UK/RU/PL/DE/EN). Onboarding page with flag-based language selection for students and parents. Phase 1.2 — translation_service.py: Batch-translates vocabulary words into target languages via Ollama LLM. Stores in translations JSONB. New endpoint POST /vocabulary/translate triggers translation. Phase 2.1 — Parent Portal (/parent): Simplified UI in parent's native language showing child's learning progress. Daily tips translated. Phase 2.2 — Parent Quiz (/parent/quiz/[unitId]): Parents can quiz their child on vocabulary WITHOUT speaking DE or EN. Shows word in child's learning language + parent's native language as hint. Answer hidden by default, revealed on tap. All UI text translated into 7 languages (DE/EN/TR/AR/UK/RU/PL). Arabic gets RTL layout support.
