Fill any subset of sensors for a district — each goes to Kafka and blends into the next 5-second window. Optionally pin the overall score at the bottom to override the pipeline on the leaderboard for ~30 seconds. Typing a place that isn't on the board is fine — it'll appear as a 30-second spotlight and then roll off automatically.

Drops the district from the Redis sorted set and suppresses future pipeline updates. Use this to clear a manual override or take a district off the board.
