+- What was implemented: Display conditions on edges with dashed styling and labels
+- Files changed:
+  - src/components/editor/edges/ConditionalEdge.tsx - new custom edge component with condition display
+  - src/app/editor/[projectId]/FlowchartEditor.tsx - integrated custom edge type, added EdgeTypes import and edgeTypes definition
+- **Learnings for future iterations:**
+  - Custom React Flow edges use EdgeProps<T> typing where T is the data shape
+  - Use `BaseEdge` component for rendering the edge path, and `EdgeLabelRenderer` for positioning labels
+  - `getSmoothStepPath` returns [edgePath, labelX, labelY] - labelX/labelY are center coordinates for labels
+  - Custom edge types are registered in edgeTypes object (similar to nodeTypes) and passed to ReactFlow
+  - Style edges with conditions using strokeDasharray: '5 5' for dashed lines
+  - Custom edges go in `src/components/editor/edges/` directory
+  - Use amber color scheme for conditional edges to distinguish from regular edges
