1//! Global KOE_ST form.
2//!
3//! The public C++ implementation routes `GLOBAL.KOE_ST` to `tnm_command_proc_koe`,
4//! and that command handler is a stub: it only returns the element itself when the
5//! chain stops at `KOE_ST`, and otherwise treats the operation as unsupported.
6//!
7//! Keep the Rust port aligned to that public source surface. Voice playback flows
8//! through other script/UI paths, not through `GLOBAL.KOE_ST` commands here.
