One more data point--I'm using Firefox on an M1 Mac mini (MacOS 15.7.7), and this web site destroys the responsiveness of this system in a way I have literally never seen before (4+ years) from anything, web site or otherwise.

I opened up Activity Monitor and CPU use looked normal but it showed the GPU was pegged at 100% as long as that page was open.
