Z-Index & Spine Skins

October was a quieter month — four releases — but they carried meaningful features. A ZIndexInspector was added to the Properties panel, letting you explicitly set the z-order of any asset. Spine skin switching at design time was wired up. A Scene Validation utility was introduced — when loading a scene, zStudio now reports any objects that are missing from or added to the saved data, so you catch schema drift early. GUI hover state was tracked in the Model to prevent accidental clicks when the cursor is over a panel.
