   - The useNodesState/useEdgesState hooks with onNodesChange/onEdgesChange handle all deletion state updates
   - No explicit onNodesDelete callback is needed - the onNodesChange handler covers deletion events

+- What was implemented: Select and delete edges functionality
+- Files changed:
+  - src/app/editor/[projectId]/FlowchartEditor.tsx - added onEdgesDelete callback
+- **Learnings for future iterations:**
+  - React Flow 11 edges are clickable and selectable by default (interactionWidth renders invisible interaction area)
+  - The `deleteKeyCode` prop works for both nodes and edges - same configuration covers both
+  - onEdgesDelete is optional if you just need state management (onEdgesChange handles removal events)
+  - onEdgesDelete is useful for additional logic like logging, dirty state tracking, or undo/redo
+  - Edge selection shows visual highlight via React Flow's built-in styling
