Replaced localStorage-only hook with React Context Provider.
Layout and page components now share the same state — switching
language in the dropdown instantly updates all text on screen
without requiring a page reload.
NativeLanguageProvider added to root layout.tsx.
useNativeLanguage() re-exported from Context for backward compat.

useNativeLanguage: Now has setNativeLang() that persists to localStorage.
Language selection carries across all pages automatically.
LanguageSwitcher: Compact dropdown component added to learn/layout.tsx
and parent/layout.tsx — visible on every sub-page (top-right).
Parent portal: Language dropdown syncs both UI language and native
language. Parents can switch language mid-session (e.g. when both
parents speak different languages).

Non-DE/EN users (parents) see a guide panel explaining:
- What this page is (vocabulary exercises from teacher)
- How each exercise type works (cards, quiz, listen, speak)
- All text in parent's native language (TR/AR/UK/RU/PL)
German/English users see the original layout without the guide.
This is the single entry point — no need to duplicate explanations
in every exercise sub-page.

Major improvements for non-DE/EN speaking parents:
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

Vocab units created via /vocabulary/units only have QA items, no
pre-generated MC questions. Quiz now falls back to generating MC
questions client-side from QA items (EN word → 4 DE options).

All exercise pages now use useNativeLanguage() hook:
- Buttons show text in user's native language (Richtig→Dogru, etc.)
- Instructions translated (Geschafft→Bitti, Nochmal→Tekrar, etc.)
- wordInNative() available for vocab translations (needs data)
Pages updated: flashcards, quiz, type, listen, match, pronounce, story.

Uses useNativeLanguage() hook for all UI text. Shows native language
translation of vocab word + audio button for native pronunciation.
Removed inline pt translations dict (now in exerciseTranslations.ts).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
useNativeLanguage.ts: Hook that reads bp_native_language from
localStorage and provides t(key) for translated UI text and
wordInNative() for vocabulary translations.
exerciseTranslations.ts: All exercise UI strings in DE/EN/TR/AR/UK/RU/PL.
Buttons (Richtig/Falsch), instructions, labels, result texts.
Next: Wire into all 9 exercise pages for trilingual display.

Text is preprocessed before TTS to expand abbreviations like
sth., sb., etc., z.B., usw. so the speaker says the full word.
40+ abbreviations covered (EN + DE). Applied to all languages.
Audio cache cleared to regenerate with correct pronunciation.

/synthesize always used the German model. /synthesize-direct uses
Edge TTS (with language-aware voice selection) and falls back to
Piper with the correct model (Thorsten DE / Lessac EN).
Also cleared audio cache to purge wrongly-generated files.

Binary data (MP3 audio) was corrupted by resp.text(). Now detects
content-type and uses arrayBuffer() for audio/* and image/* responses.

AudioButton now tries Piper TTS via /api/vocabulary/tts endpoint
first, falls back to Browser Web Speech API if unavailable.
Backend: New GET /api/vocabulary/tts?text=...&lang=de endpoint.
audio_service.py: Fixed presigned URL flow for MinIO download.
This gives the same high-quality voice as the Investor Agent
in the pitch deck (Thorsten DE / Lessac EN, MIT license).

Next.js route-level layouts provide Sidebar + gradient background
automatically for all sub-pages. Individual pages no longer need
their own wrapper divs or Sidebar imports.
- learn/layout.tsx: Sidebar + purple gradient for all learning pages
- parent/layout.tsx: Same for all parent portal pages
- LearnLayout.tsx: Reusable component for other pages
- Fixed broken <LearnLayout>}> artifacts from previous refactoring
- Removed duplicate Sidebar/wrapper code from 9 sub-pages

65 files in klausur-service packages + 3 in backend-lehrer packages
had stale imports referencing deleted shim modules.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
klausur-service: 183 shims deleted, 26 test files + 8 source files updated
backend-lehrer: 59 shims deleted, main.py + 8 source files updated
All imports now use the new package paths directly.
Zero shims remaining in the entire codebase.

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.

Turbopack doesn't support tsconfig path aliases pointing outside
the project root. Reverted to copying shared types directly into
each service. The canonical source remains shared/types/*.ts,
synced via scripts/sync-shared-types.sh.
Changes:
- Reverted docker-compose.yml contexts to ./service
- Reverted Dockerfiles to simple COPY . .
- Removed @shared/* from tsconfigs
- Removed symlinks + .gitignore hacks
- Added scripts/sync-shared-types.sh for keeping copies in sync

Turbopack only resolves tsconfig paths within the project root.
Changed @shared/* from ../shared/* to ./shared/* in all tsconfigs.
Docker copies shared/ into the project dir at build time.
Local dev uses symlinks (gitignored).

Shared types extracted to shared/types/:
- companion.ts (33+ types, was 100% duplicated admin-lehrer ↔ studio-v2)
- klausur.ts (18+ types, was 95% duplicated across 4 locations)
- ocr-labeling.ts (11 types, was 100% duplicated admin-lehrer ↔ website)
Original type files replaced with re-exports for backward compat.
tsconfig.json paths updated with @shared/* alias in all 3 services.
Docker: Changed build context from ./service to . (root) so shared/
is accessible. Dockerfiles updated to COPY service/ + shared/.

audio_service.py: Connects to compliance-tts-service (Piper TTS,
MIT license) for high-quality German (Thorsten) and English (Lessac)
voices. Audio cached as MP3 on first request.
vocabulary_api.py: New endpoints:
- GET /vocabulary/word/{id}/audio/{lang} — word pronunciation
- GET /vocabulary/word/{id}/audio-syllables/{lang} — slow syllable-by-syllable
Anton App analysis: identified 5 features to adopt (star system,
games as rewards, progress bars, listening exercises, matching exercises).
