-- Safe one-shot native visual repair ---------------------------------------
-- UI texture patches can replace the files behind Blizzard's native
-- Nameplate-Border/Nameplate-Glow paths without changing the texture paths
-- returned by the client. Keep private copies of the original Vanilla assets
-- inside BNP so those patches cannot silently reskin or blank the plates.
--
-- Apply them 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.
