✨ Features implemented:
- FastAPI backend with JWT authentication
- PostgreSQL database with async SQLAlchemy
- HTML document viewer with smart highlighting
- Note system connected to highlights (1:1 relationship)
- Bookmark system for quick navigation
- Integrated search (documents + notes)
- Tag system for document organization
- Docker containerization with Nginx

🔧 Technical stack:
- Backend: FastAPI + PostgreSQL + Redis
- Frontend: Alpine.js + Tailwind CSS
- Authentication: JWT tokens
- File handling: HTML + PDF support
- Search: Full-text search with relevance scoring

📋 Core functionality:
- Text selection → Highlight creation
- Highlight → Note attachment
