Ice-chilled cocktail temperature and dilution are coupled

Provides the physical boundary needed to reconcile vigorous shaking advice with proof-adjusted dilution. Technique can change rate and texture, but melting ice couples heat removal to water addition.

Arnold limits this formulation to traditional cocktails whose ingredients are liquor, mixers, and ice at 0°C, with chilling supplied by melting ice under simplified thermal assumptions.

There is no chilling without dilution, and there is no dilution without chilling.
