Remove Dark Edges From GIF

I have an animated .gif with transparent areas that’s showing distracting black spots around its edges. All I need is a cleaned-up version where those artifacts disappear and the outline feels smooth and seamless, as if the issue never existed.

What must stay exactly the same is the transparency, the current frame rate and animation quality, and the original colours—no shifts, fades, or dropped frames. You’ll receive the source file right here on the platform, and I’d like the fixed file delivered in the same format plus, if you wish, a lossless master (PNG sequence or layered PSD) for future tweaks.

Deliverable
• One repaired .gif—same dimensions, loop, frame order, and palette, but with completely clear, artifact-free edges.

I’ll review by overlaying the new file on multiple backgrounds to be sure no edge pixels remain. Once it passes that simple test, we’re done.
