## Summary
|
|
|
|
Deliver `@suaveplan/r3f-physics-rapier` on the genesis branch from scratch at enterprise quality. The package provides a Rapier physics engine integration for React Three Fiber, implementing the `PhysicsBackend` interface from `@suaveplan/r3f-physics-core`. It wraps `@dimforge/rapier3d-compat` (WASM); a `RapierPhysicsProvider` initialises the WASM module asynchronously and provides a `RAPIER.World`; `RigidBody`, `Collider`, and `Joint` components wrap the corresponding Rapier APIs; `useRapierContext()` exposes the raw `RAPIER.World` for advanced usage. Genesis adds structured errors, and 100% coverage.
