It's OK for a shadow to move faster than light, because a shadow is not a thing.
The same principle allows the progress of a scan line on a CRT monitor to proceed at faster than the speed of light. It's different electrons and photons showing up farther along the screen, so it's OK for the trace on your screen to move faster than light.
That does not compute.
