When an impedance trace crosses a split, reference plane repair

**When an impedance trace has to cross a split, reference plane repair becomes the last line of defense. The core goal of the repair is singular: to provide a "shortcut" for the return current—a path that is nearby, low-impedance, and short—so it doesn't have to take a detour, thereby restoring impe
