MKW_VR_STANDALONE (runtime_config.h) names the standalone headsets: the
Quest, and the Steam Frame in its Android flavour and its native SteamOS
build. They share render scale 0.8, foveation medium, the GX thread,
the game's object culling, and the headset panel's foveation and
tracked-hands rows; passthrough stays Quest-only.
The Frame's native build also sets AuroraConfig::xrHeadsetOnly, so
Aurora neither presents the desktop window nobody watches nor renders
it past the last pass the eyes sample, which Android does always (4 to
6 ms of a 12 ms GPU frame on a Quest 3).
