Research direction

Open the linked animation tutorial in Firefox on Windows 11 and reproduce the shadow banding while checking the reported console warnings. Trace the engine's shadow-rendering path used by the preview and compare the result with a browser where the issue does not occur; done means the banding is resolved without introducing new console errors or warnings.
