+ * sibling native bin/ directory (loaded via a dynamic dlopen() Next's static
+ * file trace can't see — the same blind-spot class as the LLMLingua closure,
+ * for a .so instead of a JS import). The bundle then failed at runtime with

+ * inference — reproduced live via the Dockerfile's post-build verification
