# UiProfile —— desktop / mobile presentation selection.
#
# The profile only selects presentation and input surfaces.  It must never
# change the M2 protocol or gameplay rules.  Desktop developers can force the
# mobile HUD with `--mobile-ui` (or the project setting below) without needing
# an Android build.
