🔨 Drop Tower Fracture Lab: Weibull Strength and Fragment Sizes — 2D Tower and Statistics Sheet

2D companion of the drop-tower fracture lab: tower elevation with a live drop cycle, Weibull strength against applied stress, P(fail) against height with a Monte-Carlo sweep, Rosin-Rammler fragments and the energy ledger, using the same physics module as the 3D page.
