AI Regulation Risk Classifier (2D): EU AI Act Tier Simulator

This 2D companion runs the identical weighted risk formula as the 3D version — 0.40×autonomy + 0.35×data sensitivity + 0.25×impact scope — on a flat canvas instead of stacked rings. Each falling dot is a hypothetical AI use-case; drag the three profile sliders, switch jurisdiction between the EU AI Act, US sector rules and China's model, or hit "Random use-case" and watch cases settle into one of four horizontal risk bands, with the compliance burden for that tier shown live in the side panel.
