Practice: fire streak badge, first-letter hint on wrong answers, missed-words drill session after practice completes. Test: audio-only mode with listening state before input appears, larger re-read button. Words: definition field (DB migration + admin editor + TTS playback). TTS: replace speechSynthesis with local Piper via /api/tts, WAV cached in data/tts-cache, falls back to browser voice when Piper is not installed. Dockerfile: switched to node:26-slim, installs Piper binary + en_US-lessac-medium voice. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
