# Starting a new kitty process is quite slow. With --single-instance (see
# $TERMINAL definition above) "new invocations will instead create a new
# top-level window in the existing kitty instance"[^1] to allow "kitty to share
# a single sprite cache on the GPU"[^1], so that startup is almost instant.
#
# For this to work best, launch one hidden "daemon" instance at startup so that
# the kitty process is always running, even when no OS windows exists.
#
# NOTE: `--start-as hidden` needs kitty 0.42.0 or later.
#
# Additionally allow remote_control over a socket, so that kitty-cwd works.
