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>
