Make BOS a complete, bootable, themed desktop OS
Install/boot reliability:
- Use native Calamares initcpiocfg/initcpio + explicit grub-install (nvram +
  --removable) in post-install; drop the flaky native bootloader/grubcfg modules.
- mount.conf: bind /proc /sys /dev (devtmpfs) /run + efivars into the chroot.
- bos-copy-kernel: stage kernel + write a stock mkinitcpio preset (replace the
  archiso preset). Per-service systemctl enable (fixes NetworkManager et al.
  silently not enabling due to the all-or-nothing grub-btrfs.path name).

System completeness:
- greetd + tuigreet graphical login; installed pacman.conf + working mirrorlist;
  base CLI tools (nano, micro, vim, htop, …); amd/intel-ucode; tlp + hypridle
  power management; systemd-timesyncd, fstrim.timer; wpa_supplicant wifi; Zen
  browser (republished to the [Breadway] repo).

Desktop + theming:
- Native Lua Hyprland config (hyprland.lua) with curated standard binds; kitty
  (blur) replaces foot; awww wallpaper + pywal palette (tamed to a black base
  with warm accents); GTK dark mode.
- Plymouth boot splash (bos theme: logo + spinner + status) via plymouthcfg.
- Varela Round font; Calamares bread-palette sidebar (logo/black-region polish
  still pending).

# BOS-specific finalization, run inside the installed-system chroot (Calamares
# shellprocess), AFTER the native initcpio module has built the initramfs. The
# kernel (shellprocess@kernel) and initramfs (initcpio) are in place by now, so
# this script installs GRUB and does the rest of setup. Calamares' own
# `bootloader`/`grubcfg` modules are NOT used — in this archiso layout they leave
# the ESP empty and abort; the explicit grub-install below is verified to boot.
# Best-effort: do NOT use `set -e`; a single failure here must not abort the rest.
