Accessibility

  • Decorative: the canvas is aria-hidden and ignores pointer events, so content above it stays clickable.
  • Fills its parent: give it absolute inset-0 inside a positioned element, with the text on top.
  • Pauses off screen and in hidden tabs. Without WebGL2 it renders nothing, so keep a background color on the parent.
  • Reduced motion draws one still frame.
