USP Field Theory — Blood Resonance Compatibility

This document extends USP Field Theory into the domain of biological systems, proposing that blood-type compatibility arises from resonance alignment rather than purely biochemical interaction. Each blood group (A, B, AB, O) maintains a characteristic field frequency (Δf), and transfusion success depends on whether these oscillations align within the critical resonance threshold (Δf < Δf₍crit₎). The accompanying diagram — Δf Compatibility Map (10⁹–10¹¹ Hz range) — visualizes resonance overlap between blood types, offering a new perspective on molecular field harmony. This work connects biological oscillations to broader USP Field Theory principles governing atomic and galactic coherence.
