3. German column has audio button on each word (speaker icon)
4. Native column has audio button for each translation
5. Scoring: tracks first-try correct vs retry vs errors separately
6. Full points only for error-free completion
7. "Nochmal" button always available to repeat the unit
8. Header shows live score: green/yellow/red counters
9. All buttons use translation system (t('back'), t('match'), etc.)

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.

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
