// GrammaGem — native macOS menu-bar writing assistant.
//
// Layer-1 grammar is the real **Harper** core (Apache-2.0), embedded as a Rust
// C-FFI static library (see `harper-ffi/`). Build the lib first with
// `harper-ffi/build.sh` (universal arm64+x86_64 -> harper-ffi/lib/libharper_ffi.a);
// `scripts/build.sh` does this automatically. The remaining heavyweight pieces
// (MLX local LLM, Sparkle, KeyboardShortcuts) are still behind protocol seams.

// Absolute path to the prebuilt Harper static lib, independent of build cwd.
