- Warn once with the rejected surface dimensions and original CanvasKit error
- Disable repeated cache allocation attempts until the renderer surface is replaced
- Keep direct scene rendering as the visible fallback
- Scale retained margins to a fixed device-pixel budget on large viewports
- Fall back to direct scene rendering when CanvasKit rejects an offscreen surface
- Cover the reported wide HiDPI geometry without coupling rendering to a WebGL context
- Fall back to live rendering when CanvasKit cannot allocate the backing surface
- Match retained backing metadata against the current graph preview version
- Cover null-surface and stale-preview backing regressions
