+"""Loopback shim server for the desktop update hand-off.
+
+Two GET routes: / serves ui.html, /progress serves the status file the
+orchestrator script writes ({"status": "running"|"done"|"error", ...}).
+Exists because a file:// page cannot receive events from a detached
+process. Prints the chosen ephemeral port on stdout, serves until killed.
+
+`elapsed_seconds` is stamped per request, not read from the status file:
+stages are minutes apart, so a value frozen at the last publish would sit
+still through the longest waits -- exactly the stall the page exists to
+disprove. Windows' in-process listener computes it the same way.
