arifOS Token Savings Calculator — Thermodynamic Edition
==========================================================

Token = Energy. Waste = Entropy. Governance = ΔS < 0.

This calculator frames token economics as thermodynamics:
- Input tokens = Energy input (G)
- Output tokens = Work performed (τ)
- Waste = Entropy production (ΔS)
- arifOS = Engine that reduces system entropy
