//! Shared fixtures for the world message layer's oracle-free regression tests (split by domain
//! across `tests/*.rs`). Client packet bodies are pinned to golden hex captured from the validated
//! implementation (byte-validated against `wow_world_messages` during the decision-0021 migration);
//! `SMSG_UPDATE_OBJECT` fixtures are real serialized packet bodies from that same corpus, parsed +
//! decoded here. Simple server bodies are hand-built (their layout is trivial: a few little-endian
//! scalars).
