Could we move the cubemap to public/assets/cubemap-reflection, to match the other examples? Also, what's the source and license for that cubemap?

• Adding new packing/unpacking utilities and updating unstruct implementation.
• Integrating a new vector slider control component for improved UI in the docs example.
