Engineering Design Loop: Tower Stability Optimizer

STEM education leans on one core habit: run the Design → Build → Test → Analyze → Improve cycle over and over until a solution works. This simulator makes that loop literal. Every "design" is a stacked-block tower with a chosen base width and height; every "build" is a real 3D reconstruction of it; every "test" applies a wind load and computes the actual overturning-versus-resisting moment balance from statics; every "analyze" step scores the result against material cost; and "improve" is a hill-climbing search that keeps only the changes that raise the score. Watch the stage tracker light up through each phase, or step through it by hand to see exactly why one tower shape survives a gust that topples another.
