USP Field Theory v3 — Universal Orbital and Photon Resonance Framework

This third-generation release of USP Field Theory unifies orbital mechanics, atmospheric retention, and photon curvature within a single resonance-based formulation. Gravity is redefined as a spin-tension gradient emerging from atomic-core density and rotation, eliminating the need for empirical constants. The constant T₀ = ¼ links photon deflection, orbital velocity, and gravitational equilibrium, providing a falsifiable alternative to general relativity. The framework demonstrates time-invariant stability from planetary systems to black-hole lensing, forming the foundation of a unified resonance-geometry physics.
