Two Live Demos and One Unsupported Renderer

A WebGL lifecycle test for multiple embeds, channel controls, reduced-motion fallback, and an unknown renderer key.

Multiple embeds should remain independent

The first demo is a supported renderer. The second deliberately uses an unsupported key so the article can show a useful failure state without taking down the rest of the page.

Unsupported renderer fallbackAn unknown renderer key should produce a clear local error and preserve the surrounding article.

What to verify

  • Only supported renderers create a running WebGL loop.
  • Offscreen canvases stop work when they leave the viewport.
  • A hidden tab does not keep animation running.
  • Reduced motion remains readable without forced motion.
  • A single renderer error does not blank the article.
