+
+This package is the Unity projection of the GameCult.Geometry authority. It
+depends on `org.gamecult.cultmath` for numeric primitives and
+`org.gamecult.cultlib` for CultCache/CultNet/CultMesh integration.
+
+Build it with `scripts/build-geometry-unity-package.ps1`. Do not edit generated
+plugin assemblies in the package output.
+
+CultLib-authored files are MIT licensed. Geometry sources transferred from
+CultMath retain their MPL-2.0 notices and provenance; those files will be listed
+here as they enter this package. No transferred CultMath source is relicensed.
