The progress lines only start once bytes arrive, and on a large account nothing
arrives for minutes — LoTW builds the entire report before sending any of it.
That silence WAS the complaint: the window still just said 'working'.
A heartbeat every fifteen seconds until the headers land, then the HTTP status,
then the megabytes — the first at 256 KB rather than 1 MB, so the very first
sign that it is moving comes early.
