# Lazy-loaded service modules (imported on demand to avoid heavy deps at startup):
# .audio          — TTS audio generation for vocabulary words
# .email          — Email/SMTP service
# .translation    — Batch vocabulary translation via Ollama
# .claude_vision  — Claude Vision API for worksheet analysis
# .ai_processor   — Legacy shim for ai_processor/ package
# .story_generator — Story generation from vocabulary words
