1. Removed stale 'explanations' export that broke build

3. Both columns use items-start for visual alignment
4. Impressum link added at bottom of learn layout

exerciseExplanations.ts: Match and Flashcard explanations translated
into DE, EN, TR, AR, UK, RU, PL, FR, ES, IT, PT, NL, RO, EL, BG,
HR, CS, HU, SV, DA, FI, SK, SL, LT, LV, ET.
Each exercise type gets a parent-facing explanation in the user's
selected language. No more German fallback for unsupported languages.

When a language like PT, FR, IT is selected but has no translation
in exerciseTranslations.ts, the system now falls back to English
instead of German. English is more universally understood.
Applies to: exercise explanations, button labels, instructions.

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).

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.

- LearnLayout.tsx: Reusable component for other pages
- Fixed broken <LearnLayout>}> artifacts from previous refactoring
- Removed duplicate Sidebar/wrapper code from 9 sub-pages

and empty lines in getApiBase functions.

HTTPS pages cannot fetch from HTTP backend ports. Added Next.js
API route proxies for /api/vocabulary, /api/learning-units, /api/progress
that forward to backend-lehrer internally (same Docker network, HTTP).
All frontend pages now use same-origin requests (getApiBase = '')
instead of direct port:8001 connections.

Strategic pivot: Studio-v2 becomes a language learning platform.
Compliance guardrail added to CLAUDE.md — no scan/OCR of third-party
