WebGL lighting is broken in macOS versions prior to macOS 26 Tahoe due to an apparent graphics stack bug.

01

Fixed-step simulation

Bounded catch-up, pause, reset, single-step, and observable discarded time.

02

One cross-platform runtime

Linux, macOS, Windows, and WebAssembly builds share the same engine and application model.

03

Inspectable by design

The complete application behind the live demo is presented as three readable source files.
