# --- Profile-guided optimization --------------------------------------------
# Go (>= 1.21) automatically applies ./default.pgo when building the golbat
# main package — locally and in the Docker build (which copies the repo). So
# committing default.pgo makes every build profile-guided; no flag needed.
# Refresh it occasionally (game updates shift hot paths), then commit:
#
#   make pgo-capture                       # reads port + api_secret from config.toml
#   GOLBAT_URL=https://host:9001 GOLBAT_SECRET=... make pgo-capture   # or override
#
# Port and secret are auto-detected from config.toml so a local operator can
# just `make pgo-capture`; any of GOLBAT_URL / GOLBAT_HOST / GOLBAT_PORT /
# GOLBAT_SECRET / CONFIG override the detection.
