Archetype Sub-90 Dry-Wipe Invariant (Thermal Conduction Rod Scaling (Q̇ ∝ AΔT/L), Convection Density Currents & Radiative Power (P ∝ R² T⁴)): Thermal Conduction Scaling Law: Rate Q̇ ∝ A ΔT / L ∝ d² (T2 - T1) / L. Radiation Law: Dull/black = best emitter & absorber; Shiny/white = worst emitter & best reflector.
