# Box3D built static and folded into our own shared library, so the engine
# ships and P/Invokes exactly one native file (lingua_physics.so/.dll), not
# two. Pinned to a specific commit, not a tag or branch: Box3D has no 1.0
# release yet and its API is still moving (confirmed by diffing its only
# tag, v0.1.0, against this commit — real, not hypothetical, drift), so a
# floating reference would silently start building against a different API
# than the one this shim's code was actually written and verified against.
