Interestingly, this website reliably crashes my firefox on linux while consuming 55GB of memory.

Claude's TLDR of what's causing the problem (may or may not be accurate): "That animation loop is almost certainly leaking memory: each time-step it draws new border geometry (GeoJSON/vector shapes) but doesn't free the old frames, so RAM climbs without bound. When you interact — especially auto-playing the timeline — the tab grows until it swallows all 62 GB of RAM + swap and the kernel kills it."
