The owner measured the arrowhead in Photoshop: past ~40° off the
perpendicular of the box edge, one barb crosses the tip's level and the
silhouette breaks. edgePathD now takes the target box and clamps the
final approach: the entry direction may tilt at most ±ENTRY_ANGLE_LIMIT
(40°) off the entry face's outward normal — a steeper natural approach
swings to the cone edge (same rotation side as the route), the shaft
stub and head follow the clamped direction.
Docking refined: the tip floats DOCK_GAP past the border along the FACE
NORMAL (constant gap at any tilt; perpendicular entries are bit-identical
to before — pinned). Faces are derived from where dagre's border point
sits on the target box (top/bottom/left/right all supported). Edges
without a known target box keep the unclamped geometry. Pinned: cone-edge
swing at 40° exactly, normal-gap docking, unclamped shallow entries.
