Backend portability
Browser builds use Rapier WASM 0.19.3. Native desktop, Android, and iOS builds select the
ThreeNative runtime's native Rapier 0.30.0 adapter through the threenative-native export
condition. Physics replays and snapshots are repeatable only within the exact pinned runtime
that recorded them; they are not portable between web and native builds,
Rapier versions, operating systems, or architectures.
world.raw, body.raw, collider.raw, and CollisionShape3D.raw are backend-specific.
They expose Rapier objects on web and opaque handles on native, so code that uses raw is
not portable. Per-frame movement belongs in PhysicsSimulation.step()'s reusable typed-array
input; visible transforms are returned in bulk through readVisibleTransforms().
