TNFR Cosmology: Structural Stability Analysis (Sphere vs. Plane)
================================================================

This script uses the Nodal Equation `∂EPI/∂t = νf · ΔNFR(t)` to evaluate the 
structural stability of two cosmological models:
1. The Heliocentric Sphere (Rotating, Curved, High Velocity)
2. The Geocentric Vortex (Stationary, Flat, Etheric Flow)

Hypothesis:
-----------
The "Inhabited Reality" must be a High-Coherence (C > 0.9) system.
We calculate the "Structural Stress" (ΔNFR) for both models.

Metrics:
--------
1. **Geometric Stress (K_phi)**: Cost of maintaining curvature.
2. **Dynamic Stress (|grad phi|)**: Cost of motion/acceleration.
3. **Coherence (C)**: Stability score.
