+// (src/imports.zig added this session). The header + .c live ONLY
+// under `library/vendors/sx_ffi_resolve_test/` — not the sx repo
+// root vendors/ — so the path can be found only by the stdlib
+// search branch (`<exe>/../../library` etc.), not by the CWD or
+// importing-file's-dir branches.
+//
+// `#include` triggers c_import.zig's auto-synthesis of `#foreign`
+// fn decls from the C header; `#source` adds the .c to the build's
+// object list. Together they let the sx side call the C functions
+// by their declared names with no manual decls.
