#               detectable wire pattern (KeyPress repeats, no KeyRelease)
#   setxkbmap de mid-run -> the server broadcasts XkbNewKeyboardNotify /
#               XkbMapNotify and the demo rebuilds its keymap (keymap_event)
#   de layout : z (y/z position swap) · shift+7 -> / · dead_acute e -> é
#               (xkb_compose dead-key sequence)
#
# Focus: the demo XSetInputFocus()es itself after MapNotify, so the XTEST
# events xdotool synthesizes land on it even on bare Xvfb (no WM, where the
# default focus is PointerRoot). No icewm needed for keyboard injection.
