27 parameterized, multi-tool chains over the calculator engines above — e.g. concrete-pour-estimator, loan-offer-compare, startup-runway-burn — that actually EXECUTE: POST real inputs, get every step run live with each step's output threaded into the next, and a final result. Not a 'launching soon' card.
