wordmark decals and Mavic wheel lettering, recolors rims yellow, and hides
original label meshes at runtime. These model appearance adaptations are

Current game adaptation: Mavic decals removed; Transition lettering and yellow rims
retained. game-bike.js batches geometry and adapts scale, steering and wheel animation.
