️ Node Type Legend — `Legend` constant (v1.47.2)

One Legend constant is emitted per *_Flows class (not per method). It contains a compact Mermaid diagram showing all 9 node types — shapes, colors, and the entry-arrow symbol — in a single horizontal row:

// Access at runtime:
Console.WriteLine(OrderService_Flows.Legend);

Paste into any Mermaid renderer to review the color and shape reference at a glance. The note also explains that Guard nodes show their condition as a hover tooltip.
