## Overview

This tree is a Unity package-cache slice, centered on 2D Animation rather than one standalone application. Its principal workflow is authoring a character’s skeleton, mesh, and bone weights in the editor, then deforming skinned sprites at runtime; the tree also exposes IK, sprite libraries, and neighboring Tilemap, SpriteShape, Timeline, and PSD-importer features. Paths and component roles are identifiable from filenames, but most implementation excerpts are partial or absent, so the graph keeps cross-module wiring conservative.

Main entry points: [`Boss and Coffee/Library/PackageCache/com.unity.2d.animation@5.0.6/Editor/SkinningModule/SkinningModule.cs`](https://github.com/mrkenny44/boss_and_coffee/blob/main/Boss%20and%20Coffee/Library/PackageCache/com.unity.2d.animation%405.0.6/Editor/SkinningModule/SkinningModule.cs) (Skinning editor), [`Boss and Coffee/Library/PackageCache/com.unity.2d.animation@5.0.6/Editor/SkinningModule/IMGUI/SpriteMeshController.cs`](https://github.com/mrkenny44/boss_and_coffee/blob/main/Boss%20and%20Coffee/Library/PackageCache/com.unity.2d.animation%405.0.6/Editor/SkinningModule/IMGUI/SpriteMeshController.cs) (Mesh editing), [`Boss and Coffee/Library/PackageCache/com.unity.2d.animation@5.0.6/Editor/SkinningModule/WeightPainterTool.cs`](https://github.com/mrkenny44/boss_and_coffee/blob/main/Boss%20and%20Coffee/Library/PackageCache/com.unity.2d.animation%405.0.6/Editor/SkinningModule/WeightPainterTool.cs) (Weight tools), [`Boss and Coffee/Library/PackageCache/com.unity.2d.animation@5.0.6/Editor/SkinningModule/SkinningCache/SkinningCache.cs`](https://github.com/mrkenny44/boss_and_coffee/blob/main/Boss%20and%20Coffee/Library/PackageCache/com.unity.2d.animation%405.0.6/Editor/SkinningModule/SkinningCache/SkinningCache.cs) (Skinning cache)
