# run_larson_dev.sh — deterministic run wrapper (avoids perf warm-up issues)
#
# Usage:
#   scripts/run_larson_dev.sh tput 10 4
#   scripts/run_larson_dev.sh pf   10 4
#
# Notes:
#  - Runs ./larson_hakmem directly and prints the Throughput line.
#  - Keeps logging quiet and avoids perf warm-ups that sometimes SEGV under A/B.
