//! `gseqdump <internal\path.m2>` — every global-sequence bone channel with its RAW KEYS.
//!
//! `benilla-extract m2anim` names which bones carry global-sequence channels and their periods,
//! but never the key VALUES — and for a twinkle (a scale loop on a star card) the values ARE the
//! effect: a 0→1 flicker and a 0→20 flare are the same one-line summary. Output is Blizzard
//! data — pipe it to the scratchpad, never into the repo.
