A new spot rendered as Needed the instant it arrived and was withdrawn half a
second later when the worked answer landed — the list twitched on every burst.
Unsettled spots are now invisible everywhere (card lines, counters, the
Active/Needed-only filters) until their verdict is in: nobody needs a spot
150 ms early, they need it settled. The answer map is merged rather than
replaced, so a settled line can never fall back to unknown, and the query
debounce drops to 150 ms since there is nothing on screen waiting for it.
