//! # oakundo — the undo/redo history module (Rust)
//!
//! Reimplements the C++ oakundo module. See README.md for the
//! architectural mapping — most notably the **trait-object command
//! pattern**: C++ subclassing of `olive::UndoCommand` becomes a boxed
//! [`undocommand::Command`] (closure-backed or a
//! [`undocommand::MultiUndoCommand`] composite) behind a plain owned
//! [`undocommand::UndoCommand`] value.
//!
//! ## Consumers
//!
//! Every consumer is in-process Rust: the app's edit layer
//! (`oakui::graphops` / `oakui::real`) drives the process-wide stack
//! through [`global`], `oaktimeline`/`oaktask`/`oaknode`/`oakplugin`
//! build commands as [`undocommand::UndoCommand`] values, and
//! `oakstorage` subscribes to the command-success observers in
//! [`global`]. The former frozen C ABI (`include/undo/*.h`), the
//! refcounted [`CHandle`] layer and the callback-table vtable commands
//! were deleted with the engine facade — the crate is pure owned-value
//! Rust with no `unsafe`.
