// functions — no wrappers needed. What still needs shimming is exactly the
// scaffold set: FORTIFY_SOURCE vs ImportC, memfd/mmap for wl_shm, and the
// `static inline` request helpers of the *core* protocol (surface/shm). Note
// what is ABSENT compared to ../c.c: no xdg-shell glue, no xdg-decoration
// glue, no wayland-scanner step — libdecor owns the whole shell layer.
