Replace simple open/closed arrow indicators with full spanning tree branch lines (vline, T-junction, L-junction) using the _dark SVG variants. This renders the model tree with ASCII pipe-style connectors instead of bare disclosure arrows.
- _ZToolsPartDesignManipulator: injects ZTools commands into PartDesign workbench toolbars (Helper, Modeling, Transformation) and menus via Gui.addWorkbenchManipulator() - no workbench switch needed - Sync CatppuccinMocha.qss with canonical KindredCreate.qss: tree branch indicators, header min-height, dock/actiongroup padding, spreadsheet cell editor styling, CSS border-triangle arrows
