+//      space even if the original thread's stack was the cause.
+//   2) Write a self-contained crash record to <internalDataPath>/face_sdk_crash.log
+//      (and also try to append it to the DebugLog file passed in).
+//      The record contains: signal name, si_code, si_addr, pid, tid,
+//      a synchronous unwound backtrace (PC + module + offset for each frame),
+//      and the value of any extra context the caller registered via setNote().
+//   3) Re-raise the original signal with the default handler so that the
+//      Android tombstone pipeline still produces /data/tombstones/* files.
+//
+// Safe to call once. Subsequent calls are no-ops. Must be called AFTER
+// DebugLog::init() so we know the log directory.
