## Tests

I have verified the changes with the following tests:

* **UI Validation:** Verified that `CoPE` correctly appears in the software's material selection list.
* **Preset Management:**
  * Successfully **exported** a preset containing the CoPE material.
  * Successfully **imported** the CoPE preset back into the software.
