# Matrix Runtime — Makefile

# Common targets:
#   make help       list every target
#   make build      build a local binary into ./bin
#   make test       full verification: fmt-check, vet, race tests + coverage
#   make install    build + install the binary (auto-uses sudo when needed)
#   make uninstall  remove an installed binary (and systemd unit if present)
#
# Install without root (user-local, no sudo):
#   make install PREFIX=$HOME/.local
# Production install with systemd + data dir + service user (needs root):
#   sudo make install INSTALL_SYSTEMD=1
