# generate_interactive_quant_dashboard.py
"""
Interactive Visual Experience Dashboard Generator for Quant.ai.
Generates a standalone, beautiful HTML Dashboard allowing the user to visually experience:
1. Cumulative Equity Curve Comparison (Old Baseline vs New Super-Alpha Engine).
2. Daily PnL Breakdown (8/16 - 8/22).
3. Microstructure C++ OFI Signals overlaid on Intraday K-Lines.
4. Purged CV & Deflated Sharpe Ratio (DSR) Model Diagnostics.
