ARCADE RALLY / SWITCHBACK CIRCUIT

An original short two-lap time trial. Circuit geometry, garage interface,
vehicle artwork, landscaping, colour system, directional lap gates and
procedural audio were authored for this adaptation. All visuals are browser
Canvas/CSS geometry. No external images, fonts or recordings are loaded.

Selected driving and rendering mechanics adapted from drift-racer.html by
wangzifan396-wzf: forward/lateral velocity decomposition, exponential lateral
grip, speed-dependent steering, nearest-track projection, layered road strokes,
tyres, body, glass and shadow rendering. This is a substantial new adaptation,
not a claim that the engine was created from scratch.
