# TCP receive-window + buffer tuning. Earlier attempt under HTTP
# regressed because every /frame opened a fresh socket and we ate
# the slow-start cost repeatedly. Under the streaming pivot the
# socket is long-lived: slow-start happens once, then we run with
# the full window for the rest of the session — which is exactly
# the workload these knobs are designed for. Larger WND lets the
# sender keep more bytes in flight per ACK and pushes our recv
# throughput ceiling up from ~5.3 MB/s.
