- GroupRectNode now renders source+target handles on all four sides
(top, right, bottom, left) using IDs zone-{side} / zone-{side}-t
- Handles are hover-only: opacity 0 by default, fade in on mouse enter
- Handle color matches the zone border color (respects custom_colors)
- Zone↔zone and zone↔node connections both allowed; edge type picker
(EdgeModal) opens on connect so user chooses ethernet/wifi/vlan/etc.
- Add GroupRectNode.test.tsx: verifies 8 handles rendered (4 source + 4 target)
- Fix @xyflow/react mocks in LiveView and CanvasContainer tests to include Position
- Label position toggle: inside (default) or outside the border
- Outside mode renders the label above/below the zone based on text_position
- Text size selector: 10/12/14/16/18/20px (default 12)
- Both fields persisted in custom_colors (no backend schema change needed)
- 8 new frontend tests, 1 new backend test
- Rename "Rectangle" → "Zone" in sidebar, add modal and edit modal
- Add border width selector (1–5px, default 2px) to the Zone modal
- Border width persisted in custom_colors.border_width and applied in GroupRectNode
- Fix DockerNode default icon: use Anchor instead of Package
- Add border_style option to Group Rectangle (solid/dashed/dotted/double/none)
- Group node type selector by category (Hardware, Virtualization, IoT, Generic)
- Add tests for border style feature
- New GroupRectNode: rounded rect with NodeResizer (8 handles), no
connection handles, always behind network nodes via negative zIndex
- GroupRectModal: label, font preset (Inter/Mono/Serif), 3×3 text
position grid, text/border/background color pickers, z-order 1–9
- Sidebar: "Add Rectangle" button (below Add Node), group rects
excluded from node count stats
- Save/load: size persisted in custom_colors.width/height, no backend
schema changes required
- elevateNodesOnSelect=false on ReactFlow so selected rects never
pop above network nodes
- Tests: 3 new store tests + 9 GroupRectModal tests (66 total, all pass)
