A film about its own launch, in one HTML file

From the post

I asked Claude Fable 5.2 to make a film about its own launch. Every frame comes from one HTML file it wrote, moving 16,384 particles. The visuals took one message and one fix on the black hole. I didn't edit the code. Numbers are Anthropic's. Music is ElevenLabs.
