Both are the client half of Turtle's custom systems, off the chain's own `FrameXML.toc`:
`Turtle_TransmogUI` hooks `GOSSIP_SHOW`, hides the stock gossip frame for its NPCs and drives
the transmog window over `TW_TRANSMOG`; `Turtle_ShopUI` (prefix `TW_SHOP`) is the custom
merchant/shop. Without these rows the server's trigger gossip text is what the stock gossip
window shows and neither window exists. Inspect-Talents and Guild-Bank stay out until
`ToggleInspect`/`SetTalentButtonLocation` and the GuildBank globals are built.
