"""
Multi-Plaquette Scanner for Prime Sixth-Order Flow

Systematically compares ρ_IGBP behavior across all 9 Standard Model fermion
plaquettes using genuine Wilson loop holonomy and QGT-derived curvature.

Extensions implemented:
- Wilson loop holonomy (replaces ln-ratio phases)
- Multi-plaquette scanning (all Pocket_U fermions)
- Reeb flow integration (time-aligned evolution)
- QGT parameterization (2-parameter family with curvature scalar)
