// ASM stream Phase F — top-level (global) `asm { … }`: a template-only block at
// module scope, lowered to LLVM `module asm` (LLVMAppendModuleInlineAsm). It
// defines a symbol that a lib-less `extern` declaration calls into — the
// import direction reuses the existing C-FFI extern path, no new surface.
// Built+run via `aot` (a module-asm symbol lives in the final linked binary,
// not the JIT host); aarch64-macos-pinned, so ir-only on a non-matching host.
