+Versions bumped from the original 1.0.60/1.4.0 plan: `codex/asset-guid-attribute`
+took 1.0.60/1.4.0 for its own release (replacing the asset path attribute with
+`CultInspectorAssetGuid`, then adding sub-asset key support), landed and
+released first. This branch must rebase onto and rebuild after
+`codex/asset-guid-attribute` before its own release: same files
+(`CultInspectorModel.cs`, the Studio drawers, the plugin DLLs/pdbs), so a plain
+merge would silently drop one side's binary rebuild.
