 The binding uses a three-layer architecture:

 2. **Chez callback bridge** (`qt_chez_shim.c`) -- stores Chez-provided `foreign-callable` function pointers and provides C wrapper functions that pass them to the C++ shim's signal connection APIs. Unlike Gambit's compile-time `c-define` trampolines, Chez creates callback pointers at runtime.
