StepConnectionStyle class

Step connection style (90-degree turns with optional rounded corners)

Creates connections with 90-degree turns that follow a predictable step pattern based on port positions. The corner radius can be configured to create either sharp corners (0) or smoothly rounded corners (> 0).

Uses WaypointBuilder for all routing scenarios including:

  • Forward connections
  • Loopback routing (target behind source)
  • Self-connections (same node)
  • Same-side ports (e.g., right→right)

Segment-Based Architecture

This style implements createSegments as the primary method. All path rendering, hit testing, and bend detection derive from the segments calculated once - eliminating redundant calculations.
