# ── Core installation modules ──────────────────────────────────────────────────
# These three modules form the mandatory base layer and must run in this order:
#   1. package-managers  — installs yay (AUR helper), nvm (Node.js), rustup (Rust)
#   2. core-packages     — installs 100+ system packages via pacman/yay
#   3. core             — enables systemd services (NetworkManager, cronie, greetd, etc.)
