🧪 Marble Momentum Race Simulation (2D)

A top-down Canvas2D marble run: marbles accelerate downhill along a hand-drawn switchback track based on local slope, lose speed to rolling friction, and weave side to side as they race to the finish.

⚙ Under the hood

Each marble samples the local slope of a catmull-rom switchback path to accelerate downhill, applies rolling friction, and offsets sideways with a sine-wave weave — the same momentum model as the 3D version, drawn in plan view on a 2D canvas.
