// One functional NPC placed at a fixed spot: a shop clerk, a ticket seller, a mahjong host...
// Read from Configs/FunctionalNpcSpots.json — see _build_spots.py.

// 
// Where the data comes from (three hops, none of which lives in the NPC table itself):
// 1. AgentDataSetsInteractSettingConfig says what the F key does for an AgentConfig id
// (OpenNpcShop(94100024), BuyBoatTicket(), ShowDialog(...));
// 2. ShopConfig.Position / IndoorMapFunctionPointConfig.Coordinate / IndoorConfig
// give the venue's world position — that is the anchor;
// 3. the anchor XZ is snapped onto the nearest CivilianDistricts pavement spot so the NPC
// stands on a walkable surface at a real ground height instead of on a roof or in mid-air.
// The server's only job is to announce the entity. Everything the F key does afterwards is client
// lua — the server neither validates nor pays for a purchase.
