"""End-to-end: the real script loop, a simulated Resi, and the REAL ProPresenter.

Everything except the Resi network calls is the shipping code path — event handling,
cue refresh, the estimator, and the ProPresenter pushes. Runs on the wall clock for
~30 seconds, then puts ProPresenter back how it found it.
