Tonelli's theorem selects lines with finite total interval cost. The union of the remaining active intervals consequently has vanishing outer length. Overlaps between the intervals require no disjointness.

Square-summable interval lengths and balloon radii pay for almost all transverse lines. The center positions are unrestricted.
