`play` · `0x4C` · **clientbound** (server → client)

Sets the open and filtering state of the recipe book for the four recipe book types (`crafting`, `furnace`, `blast`, `smoker`). The server sends it on join and when the state is loaded from player data; the client restores the recipe book GUI to those settings.

Sent by the server, read by the client. Listen for it with `client.on("RecipeBookSettings", (data) => …)` on the receiving side.
