Research direction

Reproduce the sparse highlighting with rust-mode under Emacs 29.1 using the same configuration, then compare it with Emacs 28.2. Identify which Rust keywords are not highlighted in 29.1 and determine whether the behavior can be consistently reproduced; done means highlighting is restored or the compatibility limitation is clearly documented.
