post_install() {
  cat <<'TEXT'
Ghost's Omarchy UI is installed. Enable it in the graphical user's session:

  mkdir -p ~/.config/omarchy/plugins
  ln -sfn /usr/share/ghost/plugin ~/.config/omarchy/plugins/ferdousbhai.ghost
  omarchy-shell shell rescanPlugins && omarchy plugin enable ferdousbhai.ghost

Summon it with `omarchy-shell shell toggle ferdousbhai.ghost`.
Shell snippets are under /usr/share/doc/ghost/shell-contrib/.
The runtime is managed separately; see /usr/share/doc/ghost/ARCH.md.

post_upgrade() {
  cat <<'TEXT'
Ghost's Omarchy UI was upgraded. Reload its QML by restarting the shell:

  omarchy-restart-shell
TEXT
}

pre_remove() {
  cat <<'TEXT'
Before removing the UI, disable and unlink its plugin in the graphical session:

  omarchy plugin remove ferdousbhai.ghost --yes
  omarchy-restart-shell

Removing only the UI leaves Ghost runtime and all owner data available.
