+# =============================================================================
+# migrate-to-lightdm.sh — switch an existing install to Plymouth + LightDM
+# =============================================================================
+# Migrates a machine that currently boots ly / greetd / GDM / SDDM / LXDM (or any
+# other display manager) to this repo's boot experience:
+#
+#     Plymouth skull splash  →  LightDM + lightdm-gtk-greeter (cyberqueer theme)
+#
+# What it does:
+#   1. Detects the currently-configured display manager(s).
+#   2. Disables every known greeter EXCEPT lightdm — for the NEXT boot only. It
+#      does NOT stop your running session, so you stay logged in until you
+#      reboot yourself.
+#   3. Runs the lightdm module (installs LightDM + lightdm-gtk-greeter, deploys
+#      the cyberqueer greeter config + skull background, enables lightdm.service).
+#   4. Runs the plymouth module (skull splash, initramfs + GRUB cmdline) unless
+#      --no-plymouth is given.
+#
+# It reuses the real module scripts under optional-Modules/apps/ so there is no
+# duplicated install logic — this tool only handles detection, teardown of the
+# OLD display manager, and orchestration.
+#
+# Safe to re-run (idempotent). Reboot to complete the switch.
+#
+# Usage:
+#   migrate-to-lightdm.sh [--yes] [--no-plymouth] [--dry-run] [--help]
+#     -y, --yes          Skip the confirmation prompt (required for non-TTY runs)
+#         --no-plymouth  Migrate the display manager only; leave Plymouth alone
+#     -n, --dry-run      Print what would happen; change nothing
+#     -h, --help         Show this help and exit
