+-- Safe one-shot native visual repair ---------------------------------------
+-- Some UI/skin addons can alter the native Blizzard nameplate border or
+-- border before BNP discovers the plate. Repair the native border only
+-- when a plate is initialized/shown. There is intentionally NO heartbeat and
+-- no layout/parent/anchor enforcement here, so BNP never fights WorldFrame
+-- movement while the player/camera is moving.
