Web sims

Read sims/README.md first; it has the contract and every command.

When to use this instead of Remotion

• Hundreds of moving things with their own rules (agents, particles, crawlers).
• A 3D object or machine the camera moves around or flies through.
• Anything that is easier to write as a three.js or canvas page than as React.

Motion graphics with type, UI and timed reveals stay in Remotion (src/).
