💡 Reverse rules: predecessors are 2x and (x−1)/3 when the latter is a positive odd integer. The edge 4 → 1 is omitted to break the 1–4–2 cycle. | ⚠️ Depth 27 produces 1,748 nodes in this implementation; deeper trees may render slowly. PNG export captures the fitted viewport. | (m,k): m = floor(n/6), k = n mod 6
