LVCAD - Layer Vision CAD Intelligence Engine
===========================================

Main system demonstration showing full CAD layer intelligence capabilities.
This is the core LVCAD system that provides engineering-grade precision
through actual CAD layer analysis.

Key Differentiators:
- Reads actual CAD layer data (not visual guessing)
- Provides exact device counts and coordinates
- Handles real-world layer naming inconsistencies
- Engineering-grade accuracy for professional use
