# ================================
# Targets:
#   make sim      — run Python DPDK simulation (no sudo needed)
#   make build    — compile C pcap implementation
#   make run      — run C pcap on default interface (needs sudo)
#   make offline  — run C pcap against a .pcap file
#   make mc       — run Monte Carlo pricing engine
#   make all      — build + sim + mc
#   make clean    — remove build artifacts
