`play` · `0x2B` · **serverbound** (client → server)

Sends the raw movement input bits: forward, backward, left, right, jump, sneak, and sprint. Sent every tick the input changes. The server uses it to steer vehicles, detect sneaking and sprinting, and for movement prediction.

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