//! V1929 (19w04b+2) — schematic-relevant subset of `V1929.java`.
//!
//! ENTITY walkers:
//!   * `minecraft:wandering_trader`: `Inventory` is a list of item stacks and
//!     `Offers.Recipes` recurse through VILLAGER_TRADE (V1929.java:13-19).
//!   * `minecraft:trader_llama`: `SaddleItem` and `DecorItem` are single item
//!     stacks, and `Items` is a list of item stacks (V1929.java:21-28).
//!
//! VERSION = MCVersions.V19W04B (1927) + 2 = 1929.
