-# Patch @seriousme/opifex socket close() — the in-process MQTT engine.
-# `this.writer.close()` returns a Promise that rejects when the underlying
-# WritableStream is already closed/errored ("Cannot close a writable stream that
-# is closed or errored"). opifex wraps it in a *synchronous* try/catch intending
-# to swallow close errors, but a sync try/catch can't catch the async rejection.
-# Under bun that floats up as an unhandledRejection, which @effectstream/log's
-# process handler turns into process.exit(1) — crash-looping the node on every
-# MQTT client teardown. Swallow the async rejection too.
+# Patch @seriousme/opifex socket close() and write() — the in-process MQTT engine.

+# reject when the underlying WritableStream is already closed/errored. opifex wraps
+# close() in a synchronous try/catch that can't catch async rejections, and write()
+# isn't caught at all. Under Bun both float up as unhandledRejections, which
