Setlist Energy and Vocal Load Planner Agent

A singer opens with three high songs, has no recovery before the long ballad, and by the encore the voice cracks. This agent reads each song's key, range, length, intensity and any transposition, and models vocal load across the set. It counts time spent in the upper range, sustained high notes, belting and gaps for rest, and finds stretches that are too demanding. It also tracks audience energy, using the singer's own tags such as opener, build or slow, to see whether the set flows. It reorders songs, remodels and loops until the load stays within the singer's limit and the energy arc works. The singer approves the final setlist. Edge case: a song transposed down for the night is modeled in the new key, not the original.
