The converged variant read as two arrows feeding one point; the two-
complete-arrows variant as two arrows next to each other, not coherent.
Owner withdrew the double-shaft idea entirely (2026-09-15); dashed was
already rejected 2026-09-14. Both relation types draw the same plain
single arrow again.
Kept: CanvasEdge.type plumbing from the snapshot (the next
differentiator will need it) and the ArrowGeom named type. Removed:
followsEdgeGeometry, the gap constants, the zoom-drift edge-path
rebuild (edges are back to a single loop in buildGeometry), the ⟹
legend entry, and the glyph tests. Vision doc records the withdrawal
and keeps the still-valid constraints.
Gates: tsc, 429/429 tests, lint, build. Live: canvas coverage 0.477,
no console errors, no legend remnants.
