Fix Fill the Blank with intelligent word selection and real sentences
🚨 MAJOR FIXES: - Remove all hardcoded French templates (60+ lines of garbage) - Replace with real sentence extraction from content - Support story.chapters, rawContent.story, and sentences arrays - Universal language support (English/Chinese, not French-only) 🎯 INTELLIGENT WORD SELECTION: - Priority 1: Words from content vocabulary (educational value) - Priority 2: Longest words if vocabulary not available - Max 1-2 blanks per sentence (random) for readability - Universal logic works for all languages (Chinese, English, etc.) 🔧 TECHNICAL IMPROVEMENTS: - Clean punctuation before vocabulary matching - Case-insensitive word comparison - Proper fallback sentences with correct target language - Better sentence filtering (min 3 words for blanks) ✅ RESULT: - WTA1B1 now shows English sentences with Chinese translations - Targets vocabulary words (turtle, umbrella, violet, etc.) - No more "Je vois un..." French garbage - Works universally for any language content 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
