Conversion for this test page:
Original character + kart skeleton animation exported to glTF 2.0, original diffuse textures embedded. Authoring studio, ignored floor, optional Christmas hat and headlight effects omitted. Texture authoring nodes replaced with the original baked colour textures. Original proportions retained, uniformly scaled to fit the 1.82 m physical vehicle width.

Steering animation follows the original markers:
Left frame 1, straight frame 21, right frame 41.
Forward steering sample = 21 - (command steering degrees / 50) * 20.
Reverse steering sample = 70 - (command steering degrees / 50) * 20.
Animation sampling uses 30 frames per second. Front wheel pivots follow actual steering angle, and wheels roll with vehicle displacement.

3D scene: custom procedural floating square island and decorative scenery.
Rendering: Three.js (MIT), see ../vendor/THREE-LICENSE.
The existing 2D Fiala physics, actor weights, observations, rewards, collision bounds and replay states are unchanged. Ground picking maps Three.js (x,z) to simulation (x,-z). Decorative trees, clouds and island rocks are visual only.
