// Phase 3.0 (FFI-linkage) — postfix `extern` on an aggregate (`#objc_class`)
// is the new spelling of the legacy prefix `#objc_class(…) extern` import.
// Mirrors 1306's runtime-class chained dispatch with the new syntax:
//   Name :: #objc_class("X") extern { … }   ==   Name :: #objc_class(…) extern("X") { … }
//
// Red until 3.1 wires the postfix-extern aggregate path through the parser
// + lowering (maps `extern` → reference, same as `extern`).
