- Memory heuristic rounds up to the nearest MB. - `simulate` reports total memory currently allocated in the info box. - All example models use `<size memory/>` rather than legacy attributes. - Regenerated `example_saved.xml` and reformatted original model in [overview chapter](https://mujoco.readthedocs.io/en/latest/overview.html?#examples). - `<size>` top-level section does not get written if empty.
