Halo's optional adapter calls and instruments the separately installed EMF
at runtime. Halo does not bundle EMF's implementation or model resources.
Users may replace EMF with an interface-compatible modified version; Halo
does not prohibit modification or reverse engineering for debugging it.
Halo's independently written code remains under Halo's own license.

Yes Steve Model (YSM) 2.6.5-fabric+mc1.21.1

This release is All Rights Reserved. It is installed separately and is not
included in Halo. The version-pinned compatibility symbols and necessary
Head-locator calculation are used under the limited permission reported by
Halo's maintainer. That permission is not a general license to YSM source,
binaries, models, textures, or other assets.

The preview extension observes the completed model preparation using an
additional method descriptor and Halo's own callback. It reuses the existing
locator math; it does not reproduce YSM's preparation or animation method
bodies. The original mod's preparation and animation execute in that mod.
