+1. Create an :ref:`mjSpec` with **all** assets.
 2. Compile each variant by mutating the spec and calling ``spec.compile()``.
 3. Compile a **base** model and create :class:`mjw.Model <mujoco_warp.Model>` from it.
 4. Override the relevant :class:`mjw.Model <mujoco_warp.Model>` fields with per-world arrays built from the compiled
    variants.
