Module frontend/ts/public/animations

Animations domain public surface.

Responsibility:

• Hosting/bridging animation engines to the app runtime (non-React).
• Stable interfaces used by animation engines.

Non-responsibilities:

• UI components/pages.
• DOM routing / app bootstrap glue.

Start here:

• createFractalHost
• FractalHost
• FractalAnimation

Notes:

• Callers own the mount element; the host owns engine lifecycle (create → run → dispose).
• Contracts are intended for main-thread use.
