"""DIMENSION 4, pass 15 (last): what does the script command GetCardDuplicate
actually return -- the duplicate ITEM ID, or just a flag?

The handler FUN_180039fb0 forwards to DAT_1802def18 vtable slot +0x18.
DAT_1802def18 is installed by FUN_180039b40 / FUN_180039ba0. Decompile those and
whatever they install, so the slot can be resolved.

This matters for the server: if nothing ever reads the VALUE of
duplicateItemId, then only zero vs non-zero is observable, and the server may
put any non-zero id there.
