# ly.sh — ly TUI display manager (cyberqueer-themed)
#
# ly is a minimal, animated TUI login manager that takes over tty1 from getty.
# Its cyberqueer theming (colormix / doom animation colours) lives in the repo's
# etc-ly-config.ini, which is also an apply-theme.sh SYS_FILES target so the
# palette stays in sync.
#
# This module was extracted from the Desktop-Environment scripts so ly can be
# installed independently of any particular DE. It is mutually exclusive with
# the lightdm greeter module (see modules.conf). Enabling ly here disables the
# other greeters (greetd, lightdm) and the tty1 getty so exactly one display
# manager owns tty1.
