Build Ground Station / build (push) Successful in 37s
Drive two independent visual layers per display target from one shared video presence signal: the fullscreen fallback/menu canvas below video and a transparent, input-transparent OSD overlay above video, reserved as the future flight OSD rendering surface. WFB and video decode stay out of the UI process; pilot video keeps rendering priority.
