# Arcline OS — top-level build orchestration
#
# The Makefile is a thin, readable wrapper around the scripts/ pipeline. It
# exists so that "make iso-server" is the one command that takes a host with
# the right build deps to a bootable Arcline OS ISO.
#
# Everything that has real logic lives in scripts/ — this file only wires
# editions to targets and passes through environment.
#
# Quick reference:
#   make help                 → this message
#   make deps                 → install host build dependencies
#   make check                → validate manifests + shell syntax (fast, safe)
#   make rootfs-<edition>     → build just the rootfs for an edition
#   make iso-<edition>        → build a bootable ISO for an edition
#   make iso                  → build all editions
#   make toolchain            → build the 11 Arcline Go tools into .deb
#   make test                 → run the smoke tests against a built image
#   make clean                → wipe build/
