A dice-only replacement for the published chase subsystem: single
accumulating LEAD track, four per-round player roles, authored six-rung
obstacle ladder in place of the obstacle deck, and a Collateral track
that costs the city rather than the character sheet.
Six-round budget with bounded Overtime so a chase fits a convention slot
by construction. One engine covers foot, ground vehicle, and spinner via
terrain layers, symmetric for PCs as pursuer or prey.
Calibration figures computed exactly over the joint success
distributions, not estimated.
