🧀 Swiss Cheese Safety Barriers: 2D Defence-in-Depth Model

Interactive 2D side view of Reason's Swiss-cheese accident model: hazards fly through layered safety barriers whose gaps erode, drift and can be patched by dragging or clicking, with a live Monte Carlo breach probability and incident-rate graph.
