//! FIFA 17 Blaze component, command and notification IDs.
//!
//! This is exactly the knowledge that must NOT live in
//! `openfut-protocol-blaze`: the generic layer routes on numbers, and what
//! those numbers mean is per-title.
//!
//! # Provenance
//!
//! The Util table was recovered from FIFA17.exe's own `getCommandName` switch
//! (jump table `0x141b17af4`). The Authentication table could not be recovered
//! statically — the name pool is Denuvo-mutated — so it was obtained by CALLING
//! the client's own `getCommandName` (`0x146e0d2a0`) in-process over ids 1..320,
//! validated by reproducing the known Util names, and cross-checked against a
//! static REST-binding struct (`0x143896a80` → `trustedLogin = 0x0B`).
//! UserSessions notification ids come from the clean, unmutated
//! `getNotificationName` jump table at `0x141b03f70`.
//!
//! Names are for diagnostics only. Dispatch matches on the numeric constants.
