Context
The Pump Room that inflates the Lung is "essentially like a pulmonary organ" — the campus's anatomy made explicit. Paired with the cardioid grounds of n.3, E.T.A. is built as a literal body: a heart-shaped hilltop with a lung buried under center court, an institution whose very architecture is the body-as-machine doctrine poured in concrete and dendriurethane. The regimen doesn't just shape bodies; it is one.
