A lite build compiled without the SDXL backend (DRAGONX_ENABLE_LITE_BACKEND off,
i.e. built with --lite instead of --lite-backend) leaves the controller null, so
the wallet never opens and the UI shows a silent "disconnected" state. The Console
status now states the cause and the fix directly ("Lite backend not linked in this
build (rebuild with --lite-backend)") instead of a vague "unavailable".
