Interview Prompt
A monitoring export hands you per-minute throughput readings in `nums`, and you want the busiest sustained stretch of exactly `k` consecutive minutes. Return the highest average over any contiguous block of `k` readings, which can run negative when traffic dips below baseline. Return `None` when there are fewer than `k` readings to fill a single block.
Summary
The sweetest stretch in the sequence.
