# Signal Handling Configuration matching the original behavior:
# Restarting sends SIGINT: Application flushes logs and exits gracefully (Read-Only Mode NOT triggered).
RestartKillSignal=SIGINT

# Stopping sends SIGABRT: Application triggers Emergency Read-Only Mode (updates pinned BPF map) and exits.
# NOTE: Because BPF maps are pinned, Read-Only mode persists in the kernel even after the service stops.
