/**
* Should the Electron app be pinned to the X11/XWayland ozone backend? True on Linux
* unless we're on a natively-supported Wayland compositor (Hyprland/Sway) or the user
* explicitly opted into the (unsupported) Wayland backend — which is reported by
* {@link enforceUnsupportedWaylandMode} instead.
*
* The overlay relies on `setAlwaysOnTop`/`moveTop` to stay above mpv; those are no-ops
* under a native Wayland surface, so XWayland is required for parity with Win/macOS. An
* explicit `ELECTRON_OZONE_PLATFORM_HINT=wayland` is still overridden to x11 here (the
* Electron Wayland backend is unsupported); the Hyprland/Sway case is left untouched so
* {@link enforceUnsupportedWaylandMode} can report it.
