Failed to create WebGL vertex array

Error message

Failed to create WebGL vertex array

What it means

Thrown when `gl.createVertexArray()` returns null during linearGradientTint setup. The VAO encapsulates the fullscreen-quad attrib layout. Null only occurs under context loss or VAO-handle exhaustion.

Solutions

1. Pair setup with cleanup and reuse cached state.
2. Recover on `webglcontextlost`/`webglcontextrestored`.
3. Reduce simultaneously active WebGL effects.
4. Restart workers showing GL handle growth.

try {
  setupLinearGradientTint(canvas);
} catch (err) {
  renderWithoutEffect();
}

When it happens

Trigger: Many concurrent WebGL effects exhausting VAO handles; setup on a lost context; constrained driver VAO limits reached.

Common situations: Dozens of stacked effects per frame; long-lived workers; headless Chromium leaking VAOs.
