Single-script builder (nosignal.sh) that turns a stock Arch Linux ISO into a fully-offline installer for a themed Hyprland + caelestia (Quickshell) desktop: matching SDDM greeter, Btrfs/Limine bootable snapshots, chwd-style GPU detection, and a curated "os updates" layer (keybind cheatsheet, settings panels, system polish, on-box management skill). See README.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# 1. nosignal-reboot-check -> ~/.local/bin (helper + desktop notify)

# 2. 95-nosignal-kernel-reboot.hook -> /etc/pacman.d/hooks (root; terminal warn)

# Re-runnable. The pacman-hook step needs root; if not root, it is skipped with a
|
|
# notice (run once as root, or let the builder ship the hook in the ISO).
